This is a Triple J Podcast. Okay,

0:02

did you see the Aurora Australis? Either

0:05

in images or did you see it with

0:07

your own eyes? We had a question about

0:09

it in this week's episode of Science with

0:11

Dr. Karl. Plus, why do op shop clothes

0:13

always have that smell and op shops in

0:16

general? And what are the

0:18

different types of photographic memory? I'm

0:20

Lucy Smith, let's get into it. Shh.

0:25

Karl, how you doing? PG Keene,

0:27

apart from a slight cough because there's

0:29

so many babies around the place at

0:31

the moment that we're running a kind

0:33

of Petri dish plague center baby jail

0:35

at our place every Wednesday and Thursday.

0:38

You know what I went to a playmates

0:40

on Saturday morning, if you will. One

0:43

of those big jumping pillows with the, it's

0:46

like a jumping castle, but it's got

0:49

all the different slides and things in

0:51

it. And it was fabulous, but I

0:53

just thought, there's just so many germs

0:55

in here. Love these kids, a lot

0:57

of germs. I

0:59

actually just something happened, speaking of coughing, I just took

1:01

a swig of tea before we jumped on

1:03

the mic together. And then it just had did that

1:05

thing where it went down the wrong way. Oh, is

1:07

that irritating when it does that? Because you got a

1:10

sore throat, and you want to go away and you

1:12

have some water and it goes the wrong way. And

1:14

you're coughing for 15 minutes instead of not do. What's

1:16

happening in our bodies when something quote,

1:18

goes down the wrong way? You've

1:20

got a little flap valve. So when stuff

1:22

goes into your stomach, it is

1:24

on a pathway. So when it goes into

1:27

your esophagus is on a natural

1:29

pathway, esophagus, stomach, small intestine,

1:31

large intestine, out in the fullness of

1:33

time. You do not

1:35

want stuff to go into your

1:37

lungs because there's no out. So

1:41

you've got yourself a hyperdeveloped, we're

1:43

humans, cough and sneeze reflex.

1:46

If anything comes close to going in,

1:48

it goes out. And once I did

1:50

the weird thing at a party of

1:52

accidentally swallowing some ice, and

1:55

it was a bit maybe the size of the tip of

1:57

my little finger or something, and I could feel it gradually

1:59

melting. Way it is or her promise me see

2:02

you as a we're was in my chest or

2:04

at is our had a since his at his

2:06

of cold will heat in my lungs with on

2:08

that pony I do oh. My gosh, that is

2:10

a little bit scary when that happens about. It

2:12

is is goods Wade was getting

2:14

better rather was that was less

2:16

scary. Are we ready to get into

2:18

some questions? to the audience? Let's a duet

2:21

I case. I always thought just in been

2:23

gutted you disastrous for success in. A

2:26

doctor's quick question for years When

2:28

I'm you know told environment, the

2:30

cold or it gets the less

2:32

sense of smell get to the

2:34

point you for going to say

2:36

I'm walking for each I have

2:38

no sense of smell at all.

2:40

Ah what causes that? Rights As

2:42

a South. As

2:44

Yes or the A can be any

2:47

temperature rising from twenty to really really

2:49

cold like a walking fruits and is

2:51

walking fridge or freezer. Of

2:54

phrase odd that sign so like fridge or

2:56

freezer just as soon as it gets really

2:58

good told or com snow to the

3:00

fridge is plus four degrees. And

3:03

a freezer his mana sustain so he

3:05

has a different ballparks. You have got

3:07

a wonderful bunch of stuff on the

3:09

from the site called the Nose and

3:11

in the upper A with and in

3:13

the of the jews none of us

3:15

are says the knows the behemoths so

3:17

by the time the air. In.

3:20

The freezer which is say Moniz if

3:22

they both have a guest your lungs

3:24

it is as thirty seven degrees C

3:26

and is being cleaned. So

3:29

you've got a humidifier year as seen

3:31

on the front of your face. You

3:33

know it's not just the the whole

3:35

of the glasses. Now normally. Is

3:38

gives up to temperature pretty quickly but

3:40

if you're breathing really cold air your

3:42

nose the at a party or knows

3:44

where you do the smelling a pause

3:46

the olfactory proceedings is is it is

3:49

cold so it is is not a

3:51

thirty seven degrees C is maybe five

3:53

or ten as does not working as

3:55

at temperatures wealth in general the rate

3:57

of a chemical. Reaction Doubles.

4:00

Maybe ten degrees C. so's He

4:02

had a really strong smell. You.

4:04

Smell it but every to smelling normal spells as

4:06

really cause you're going to smoke because is it

4:08

as a price you pay for Still the yeah

4:11

what a humidifier! The it's two hundred percent humidity

4:13

and thirty seven degrees C. And so the spawn

4:15

topic isn't your lungs. Oh.

4:19

Thank you for. Source Exhaust without Maisie

4:21

in Victorian. Amazing! We saw

4:24

a lot of photos oz.

4:26

A beautiful. Sight in the sky as the weekends

4:28

you want to insult us about it. Yes

4:31

side of it so I'm like question

4:33

is was legally the jets the as

4:36

since let's see or or as tell

4:38

us which was incredible. Oh throughout

4:40

so jealous resisted that are are are

4:42

have seen as a little bits of

4:44

never seen an incredible have seen all

4:46

of the that this pretty good as

4:48

on never seen above the spits web

4:50

of it was describing is incredible I

4:52

had to school. And it

4:54

made me wonder if the A

4:56

rural this close by magnetic stone

4:59

and the men's magnetic force a

5:01

sex the ocean side season will

5:03

the aurora a the say. Ah,

5:06

Okay so what what? What it

5:08

is about the moon and sun

5:10

to a lesser degree this exercise

5:12

is the gravity. Know the magnetic field

5:14

but the gravity and the moon's

5:16

over his. He does look closer

5:18

so is it has two thirds

5:20

of the tos the sun for one

5:22

third. So this is sort of

5:24

run through. has era happens so

5:27

eager to be the background. So you've

5:29

got the sun and then you

5:31

got the earth going around. The

5:33

sun's caught a sweeping out most

5:35

of. The skinny don't as a ring

5:37

so he we go your own sundaram thirty

5:39

kilometers second now the first things can happen

5:42

that you see this guy who say is

5:44

a meet you so you going round a

5:46

city who is the second then suddenly this

5:48

rock is in the pathway of the earth

5:51

or the as runs is really easy as

5:53

from behind all the way you the something

5:55

of flesh is in the skies for few

5:57

seconds like as as number one number. Who

6:00

among your storm was a meteor

6:02

Storms the best one on record?

6:04

Is. The li in his in early

6:06

November in the you know, I think

6:09

the second of that ember in ninety

6:11

sixty six in the Usa from two

6:13

to four the morning when those seeing

6:15

a hundred meteors per second. That.

6:18

Is this a current records and when have as it

6:20

is in the same way that the earth getting around

6:22

the sun. Sleep. So little mini

6:24

ring or don't have since com us

6:26

to the same since personal social of

6:29

the or elliptical like a football said

6:31

they com mean cosmic our way out

6:33

and com minutes and of issue of

6:35

times the comet which is made of

6:38

ice and rubble. The. Ice evaporates

6:40

a summer comes close. Say got this

6:42

ring of rocks in a little orbit

6:45

and the earth runs into that ring

6:47

of rocks and. Not

6:49

as easy to so I think the

6:51

next one will be in two thousand

6:53

thirty three. So any way to make

6:55

sure your that puzzle will would have

6:57

a real good and com predicted with

6:59

their current technology and the serve on

7:02

is quite different than you are now.

7:04

The sun is burning six hundred and

7:06

twenty million tons of hydrogen every second

7:08

as a lot and turning. it's. Is

7:10

six hundred and sixteen million

7:12

tons of helium and about

7:14

one million tons every second.

7:17

Of charged particles like electrons and

7:19

protons south a messy but the

7:21

sun in the middle so so

7:23

system and all the time is

7:26

throwing out for was enormous surface

7:28

area is throwing out a million

7:30

tons a second. Before an

7:32

aurora. What happens is you have

7:34

a small part of a sudden

7:36

throw out not a million tons

7:38

in every direction. But. A busy

7:41

it. And aimed at the earth

7:43

there are say the small part of

7:45

the some is something maybe twice the

7:47

size of the Us and some my

7:49

physics made using as it's been a

7:51

goggles rebels and look at this sudden

7:53

see the sunspots the cause that's so

7:55

this bowl of hot guess a billion

7:57

or more times come at the years

7:59

his. The a magnetic field. Can't.

8:01

Really, get through. it's but it is

8:04

gets funneled to the north and South

8:06

magnetic poles. North exit polls is in

8:08

one top right hand corner of Ten

8:10

Deaths South Magnetic Pole roughly halfway between

8:12

Adelaide and the South Pole in the

8:15

middle the ocean. The Ups and then

8:17

if you look of the north and

8:19

south make that he posts and you

8:21

do a donor around them. About

8:24

twenty degrees in radius either. has his

8:26

ninety degrees between the north and south

8:28

pole and the quite are you know

8:30

of course a circle. say do a

8:32

donut around the north and south many

8:35

posts and nestle going to get the

8:37

best aurora but this was so big

8:39

as he get of saw that was

8:41

like four point nine. it was really

8:43

beats that it was happening a way.

8:45

I saw that twenty three bed nets

8:47

what you're saying. South. Yeah, I

8:50

know you're this. Becker was a question again. I'm.

8:53

If. It was caused by magnetic stores

8:55

and had the means magnetic force affects

8:57

the ocean tides. Well. The Aurora

8:59

sake the say. Oh Willie Aurora

9:01

six seats not oh lost his

9:03

is putting outlaws and roughly one

9:05

third of deep ocean creatures deal

9:07

with was a use lot of

9:09

the ways yeah Katie they give

9:12

of what off as a lot

9:14

from the surface really doesn't make

9:16

it much down past fifty meters

9:18

also so the case probably not

9:20

they are lawyers are to simplify

9:22

should not probably not like. This.

9:24

Things maybe. He looks amazing! Think.

9:27

He we've got civil in here now so

9:29

on you are having a conversation with your

9:31

husband the other night with Conan. Morning

9:33

doctors say we were having

9:36

an attack. In regards to hair

9:38

and body fat, say, we have a

9:40

freak out of the hairdressers and a

9:42

bothersome what not is get her cats

9:44

and what. But.

9:47

Yet when it comes to my husband's

9:49

under on as he obviously doesn't say

9:51

then he doesn't turn them yet. they

9:53

never seem. To. Grow any

9:55

longer than what they are.

9:57

Ah, with updates evolution so.

10:00

It. Was a god he eyebrows and

10:02

the his everywhere in your body there

10:05

is a program is l gross so

10:07

far as into stop. And

10:09

then pushed out and of on

10:12

comes in. So typically for a

10:14

teenage male the hair length is

10:16

about three cause the motor and

10:18

I had when I was the

10:20

he beats here almost my buttocks

10:22

but a woman can go when

10:24

the half made as it is

10:26

an exceptional case and then others

10:28

so ram specs so is the

10:30

eyebrows you can have abnormally long

10:32

has it was as you do

10:34

the rising according to my daughter

10:36

and you pluck them desert mods

10:38

and it's if. As I soaked

10:40

is just as the program has

10:43

evolved over the last several hundred

10:45

thousand two couple million years who

10:47

have been evolving says the here

10:49

is is part of the body

10:51

has the same as as required.

10:54

Like with the evolution is that

10:56

the two legged animals became sort

10:58

of more presence around sixty million

11:00

years ago after the as a

11:02

docile.as succeeds and in about seven

11:05

million years ago at the same

11:07

time as we. Move

11:09

the creases would become us lucy so loose

11:11

seats fully grown was the saw his with

11:13

a sore thumb up says a bet you

11:16

rib cage and lucy was this of been

11:18

in is yes see had lost her body

11:20

he says a split was one way to

11:22

lucy was will have issue the to us

11:24

out this in the sky with diamonds the

11:27

front cover the national geographic famous than sister

11:29

vast and the other moments the chimpanzees and

11:31

bonobos the with had seven million years when

11:33

we lost this sort of their body. hes

11:36

to get really ass and along the way

11:38

because. Here is made of

11:40

protein. And we had another

11:42

mutations took their protein and put into

11:44

our brains. We started get smarter says

11:47

second stage begin to really happens. About

11:49

thirty million years ago we started doing

11:51

fire and and of tells. Me

11:54

that says so Programs is as part of

11:57

the progress. This is a Titan controls as

11:59

man. Ah

12:02

in can bras are wrong with

12:04

you? What's your question? The

12:07

morning doctors I was just wondering.

12:10

Sit. Luck with colds and flus. How

12:12

you can build up healthy bacteria to

12:14

fight those things and can build up

12:16

a little bit of immunity? Can you

12:18

build up these same top of immunities

12:20

when it comes to food poisoning? My

12:22

brother and I'll always eighteen questionable and

12:24

suspicious things and always as wondering is

12:26

that some in a computer community opposite

12:28

can union. Me an example of

12:30

their questionable suspicious things. Ah

12:33

well there we have a little farm that

12:35

shop at home and as a few youngest

12:37

that we're going out and then so we've

12:40

been on that for the last couple days

12:42

are not enough. That's what's make my stomach

12:44

a little bit upset. What is yours is

12:46

by go ahead you may near the who.

12:49

Three dates Yes yes. Afford

12:51

season playing with fire. little bit

12:53

antsy. Yeah. Always and can

12:56

say com we reckon. He's

12:58

probably size. In the Usa,

13:00

you've got seventy six million

13:02

people. Who is? You get

13:04

food poisoning, overpopulation of three

13:06

hundred million, three hundred thousand

13:08

and up in hospital and

13:10

about four thousand.united Kingdom about

13:12

five hundred dies even food

13:14

poisoning Strozzi probably listen that

13:16

maybe half the property pretty

13:18

sight of rules. Ten hidden

13:20

immunity year you will have

13:22

a times did immunity poses

13:24

being there and surviving ah

13:26

and says he. Survived. In

13:28

that gives you your your be the new these

13:30

an interview in a culture for a long time.

13:32

What is your house are your thoughts. To.

13:35

Some degree his opponent right happens when you

13:37

go to a different house with a have

13:39

different bacteria and then you're really susceptible to

13:41

it. But do you do because up a

13:44

bit of immune the but then people do

13:46

good cook from it's and then is a

13:48

five second rule way or have difficulty believing

13:50

that because but they are you the believe

13:53

is a peculiar route seventy got stopwatches so

13:55

the sit around the floor nuisance sooty goodness

13:57

comes from heaven as i get back off

13:59

guard. The start counting was fundamentally

14:01

get the father's they will jump

14:04

on. I'll yes. So the latest

14:06

summary is this the vast majority.

14:09

The bacteria get the immediately upon

14:11

landing and is a increase but

14:13

his appears upon the services. Your

14:16

worst case. Is wouldn't go

14:18

what with Sabi foods. like a steak

14:20

that is soft on the surface or

14:22

watermelons landing on a nice flat surface

14:24

says any got intimate contact of a

14:27

large area the officers are you get

14:29

sued by hearsay might have this an

14:31

apple was his skin on up and

14:33

it lands on a carpet and Aqaba

14:35

saw the whole bunch of little pointy

14:38

single says nautilus surface area so or

14:40

have doozy bit of a rub and

14:42

you probably be safe and time. Does

14:44

that help? Archie? To the how della terza

14:47

so you can do up there for me

14:49

it is eat My brother climbed the they

14:51

are in.i and i got a mafia ride

14:53

the train think oh I'm lucky their family

14:56

we the same thing and I have on

14:58

gusto get traveling and they dub it's these

15:00

things size like I used to be really

15:02

prone to seasickness. now the new to us

15:05

everything changes his time I came under. Seventy

15:07

minutes, maybe in a year and let us know, hey, don't.

15:10

Like it will. S we've

15:12

got honey from non the honey I

15:14

you've got question that pins and needles.

15:17

Yes, Tell a dog does that

15:19

look silly is I was wondering

15:21

i'm at night Sometimes when I

15:23

get into Nato is sometimes it's

15:25

like a fuzzy see is ceilings

15:27

that then there are other times

15:29

that it actually is quite painful

15:32

and like there are Nato is

15:34

sticking up back in your face

15:36

sizes to know. What?

15:38

Would cause the difference in

15:40

that. A hurry getting these pins and

15:42

needles is because you've gotta say for example

15:44

the upper body your ah i'm rusty over

15:46

the back of allows for rules on taunts

15:48

or is it was the legs you cross

15:50

your knees and you putting pressure on the

15:52

saw at a nerve or you missing you

15:54

seat so her address would you do to

15:56

make this happen. it's probably advice

15:59

so it's maybe a little bit

16:01

of pressure on the sciatic but also like just

16:03

then I was sitting on the train and I

16:05

kind of had my feet raised a little bit

16:08

and I got the painful

16:10

the painful pins and needles in

16:12

my feet but other times it just

16:14

is like your foot's just gone dead.

16:18

Okay is this a common thing with you when

16:20

you lot like it

16:22

happened more than once a year? Yes I

16:27

probably should sit a bit better maybe. Maybe.

16:30

Scaring her Carl, you're scaring her. Okay so it's

16:32

probably worthwhile just mentioning it to your GP that

16:34

you're prone to it and what they might do

16:36

is think about the fact you might have a

16:38

bit of a tight output

16:40

on your spinal cord

16:42

where the nerves come out. So

16:45

the nerves come out through little gaps between the

16:47

vertebrae they're the little blocks of bone that make

16:49

your spinal cord and sometimes the holes can be

16:52

big which is good and sometimes the gaps can

16:54

be small so you might be getting a bit

16:56

of pressure combined as you said with not sitting

16:58

square. The nerve is not

17:00

just a single thing it's a whole bunch of

17:02

fibers and they're all in parallel and you might

17:05

be putting more pressure on the

17:07

outside ones over to the left rather than

17:09

to the right. So in general if you're

17:11

lucky you'll just get a general blocking of

17:13

the whole thing and it becomes numb but

17:16

if you put too much pressure on one

17:18

of it I don't know how that might

17:20

lead to like a sharp pain.

17:22

We need a neurologist to ring so that's

17:25

all I got for you. I'm sorry I failed you there

17:27

a bit Dr. Honey. No that's

17:30

totally fine I'll go get checked

17:32

out. It's

17:35

more about yeah just that intensity sometimes

17:38

it really does you really need

17:40

to take a breather sometimes when you got pins

17:42

and needles. Yeah in fact you should

17:44

have a breather all the time every

17:46

hour on the hour. We've got a question here

17:48

from Nick on the Central Coast he's at work so he can't

17:50

call but he wants to know

17:52

saunas and cold plunges very in at

17:54

the moment he said

17:57

he noticed that when he sits in the sauna his nose is not a

17:59

good thing. Some banned from the hot air

18:01

is this damaging at all to the

18:03

respiratory? System almost certainly not as part

18:06

of what your body could help the

18:08

he he's generating in sauna sweat like

18:10

crazy and so long as these hydrated

18:13

he can take a sauna up to

18:15

ninety five degrees C we say do

18:17

every year in the South Pole of

18:20

the three hundred clubs and one of

18:22

my mates was exposed to the air

18:24

at minus one hundred and the first

18:27

he he did say it's the eagles

18:29

frankie body through temperature change on his

18:31

skin a three hundred seventy degrees. On.

18:34

A day when the gum meteorologists to spend

18:36

the time. it's says of the a temperature

18:39

outside as low as minus one hundred therapist

18:41

is in a time so you go to

18:43

the sauna nude apart from Suzuka a close

18:46

because. The. Your sweat and

18:48

then you'll get ice and a mud

18:50

pretty skin and in jamaica plain sausages

18:52

go naked. pauses and so they also

18:54

they are the sorts and they're at

18:56

ninety five degrees seats and is is

18:58

a bit hot but as only on

19:01

the upper part and it's it provider

19:03

you generating enough moisture you you're almost

19:05

certainly okay. Is is any anti surges

19:07

can give me more specific information please

19:09

reams and thence the go to the

19:11

cold. Or musk idea

19:13

of a laser okay but the first

19:15

year my my did he was so

19:18

taken slow they old for that slowly

19:20

into the complete darkness says one hundred

19:22

percent doc all dates and and then

19:24

they trot slowly naked Around the South

19:26

Pole is a physical South Park bigger

19:28

little stone is markets and I come

19:30

back inside the second he got a

19:32

bit cocky alums one of his most

19:34

a way bizarre steps and the cold

19:36

a came down low us and he

19:38

had a coffee db the for spot

19:40

of his up at the lights off

19:42

for. Couple away south's to that

19:44

degree. He can cause damage and

19:47

really the human body didn't evolve to

19:49

breathe air up at around the same

19:51

degree say so you might be. he

19:53

could cause of damage with in general

19:55

providing generate enough sweet and yes a

19:58

conditioning sister's wedding Find your okay. Please

20:00

really into his decision. I could be getting out

20:02

of into trouble. He's saying see, have a cyborg

20:05

reign of knowledge and ice fang if you're not.

20:07

In the sauna said that long. As

20:09

well as as I recommended Time

20:11

Thoughts it. Will have to say

20:13

staying with nostrils seemed in Melbourne

20:15

What's your question? One.

20:18

Of his I'm an artist that after

20:20

another drinking and only way up from

20:22

just. Open Source this was dismayed

20:24

but also to our friends in my experience

20:26

at same size as wondering why you get

20:28

congested. Not. After drinking. Is

20:31

real and happens done as. Well

20:36

as will grab this a really good

20:38

ones what he is real the some

20:40

sort of he said when you drinking

20:42

alcohol if you drink beer for every

20:44

two hundred mills of be you drink

20:46

you and you drinking you and a

20:48

free to the as say get dehydrated

20:51

to they could be a reflex swing

20:53

we use load you to she's up

20:55

with too much were is is bullets

20:57

is before he had at chez have

20:59

a drink in one he was wake

21:01

up and still be dehydrated. I'm

21:03

probably wake up and still bit

21:05

say hydrated. Ah any city I suggest

21:08

that was is the exact opposite doubt

21:10

know. Sometimes I you know when I

21:12

have my salah my morning shower tonight

21:15

as I like to see nice sitting

21:17

in the same for a little bit

21:19

and then discuss in i. Don't.

21:22

A couple of Bushman think he's seen we the same.

21:24

Hang since his majesty and I. Ah,

21:27

blowing on. Get it out? Yeah yeah. But

21:29

it but breathing in the same I guess it

21:31

is similar to the sauna that you know that's

21:33

kind of one of the first things I do

21:35

after not out to so I can clear out

21:37

the system so thin you're not alliance. A good

21:39

one of the is is as nice home for

21:41

me off but remember that is hospitals with the

21:44

kids would come he was as was sometimes we

21:46

just check I'm in a room with a shower

21:48

just stream the room up and we were just

21:50

burn up hot were like crazy it's because it

21:52

in what the kids.and so we just sit there

21:54

and esteem is and grizzlies Whoop it us. Of

21:56

gonna find out more better at her know

21:58

bedrooms his spurs. Okay, fair. We'll

22:01

see how we go. We've

22:05

got Mattie in Midagong here. Now Mattie, you

22:07

have been a long time listener of Science

22:10

with Dr. Carl and you have, I don't

22:12

know what's going on, we've got a bit

22:14

of a nasal themed episode going at the

22:16

moment. Mattie, what's your question? Many years

22:18

ago, Dr. Carl, you mentioned that

22:20

if you plucky nasal hair out,

22:23

you either sneeze or you tear

22:25

up. Now when I do

22:27

it, I don't. Now I'm ADHD, OCD

22:29

and PTSD, I've got a really high

22:32

pain tolerance. But I'm

22:34

just wondering, I can just

22:36

yank out a finger and a thumb full of

22:38

nose hair and no reaction at

22:40

all. What about eyebrow

22:42

hair? Oh,

22:45

I don't, I don't like around with them. Mattie's

22:48

not touching them. They really do. No,

22:51

no, that's what the beard

22:54

trim is for. Fair enough. Ah,

22:56

the Turbo Groover 2001. Gotcha. Okay,

22:59

so it happens via the trigeminal

23:01

nerve. So the trigeminal nerve deals

23:04

with sensation to your face.

23:06

You've got one on the left side of your

23:09

face, one on the right side of your face

23:11

and it's in three boundaries, above your eyebrows, sorry,

23:13

above the corner of your eye, from the corner

23:15

of your eye to the corner of your mouth

23:17

and from the corner of your mouth to the

23:19

top of your neck. So normally

23:21

there's a little bit of cross

23:23

wiring, so you get

23:26

a pain reaction and then it's

23:28

cross wired across to make tears.

23:32

This is probably because, I mentioned

23:34

this before with sneezing, that it is good to

23:36

sneeze, to stop stuff coming into your lungs,

23:38

it's good to have tears, to stop dirt

23:41

getting in your eyes. And so in your

23:43

case, I'm sorry to hear about your whole

23:45

galaxy of things, the

23:47

ADHD and anything else.

23:50

I enjoy it.

23:52

I have broken my nose seven times, so

23:54

that might help me,

23:56

Luke Focky. In

24:00

this case, all I can say is it just

24:03

goes down to individual variation combined

24:05

with your background of the various other things that

24:07

have been happening to you. I can't go any

24:10

deeper than that without knowing more about you. We

24:12

had the iron guts earlier. Matty, I reckon

24:14

you've got an iron schnoz. That's what

24:16

it is. It's a food bus many times.

24:18

Thank you very much guys. Thank you. Gosh,

24:20

thanks Matty. Is that a good name for

24:23

a band? The Iron Schnoz? The

24:25

Iron Schnoz. I think so. Absolutely.

24:27

I mentioned about congestion after

24:29

a night out, particularly when

24:31

you've been drinking alcohol and

24:33

someone has hypothesized, congestion after

24:35

drinking, the histamine content in

24:37

alcohol. Oh my God. I

24:40

mentioned it happens to me and I am very

24:42

prone to that. What sort

24:44

of alcohol would that be? Would that be

24:46

you're looking at either your spirits, your wines

24:48

or your beers? Is that the three main

24:50

classifications? I think maybe it happens to me

24:52

the most after wine. Okay. We've

24:54

got the congenus which is

24:56

a fancy name for chemicals that

24:59

taste good but have other

25:01

side effects as well. Okay. We've

25:03

got Harper right here. Harper, what's your question?

25:06

Hi Doctor. Thanks for taking my call. So

25:10

my question is what is

25:12

the difference between a photographic

25:14

memory and an idiotic memory?

25:16

I think I'm saying that right. I've

25:18

been looking into it a little bit

25:21

but I'm sort of struggling to find

25:23

too much that distinguishes them because a

25:25

lot of sources keep saying they're like

25:27

the same thing but if

25:29

they're the same thing, why do they have different names? I

25:33

was hoping for clarity I guess. What

25:35

is, and this could be answering the question entirely,

25:37

what is an idiotic memory?

25:40

An idiotic memory is that you look at

25:42

something and then for a brief period of

25:44

time, that seems to be the difference. Brief

25:47

period of time, you can say, oh the top left

25:49

hand corner is this, oh you want to know what's

25:52

in the right hand corner, that was there and you

25:54

can describe it for a brief period of time. An

25:56

idiotic memory is real and it

25:58

is... more common in kids

26:01

and you tend to lose it as you get

26:03

older and the photographic memory is

26:05

the same thing but you keep

26:07

it for longer and in general

26:09

it is not present, it

26:11

doesn't exist but there's a

26:14

book called Born on a

26:16

Blue Day and this

26:18

is by a guy who has massive synesthesia

26:22

where all the nerves are sort of jumbled together

26:24

and in fact that's a normal state and he

26:26

reckons that the rest of us are just sort

26:28

of slightly crippled and so when

26:31

he thinks of the days

26:33

of the week they have colours and there's

26:35

various musicians who when they pluck

26:37

the keys or tap

26:40

the keys on a keyboard or pluck the strings of

26:42

the guitar they see bubbles of colour in front of

26:44

them and they just rearrange how they

26:47

move their fingers to make the

26:49

colours look better. So this guy,

26:51

the Born on a Blue Day

26:53

guy, he seemed to have photographic

26:55

memory but he was like one of them. He

26:58

went to Iceland, he learnt Icelandic in three

27:00

days and was able to crack jokes on

27:02

TV. He's not like you and me right?

27:05

Saying I couldn't do that? No. He's not like me. So what he

27:07

could do would be

27:12

to look at a

27:14

photograph or fly over a city

27:16

when he comes into it and then over the

27:19

next few days draw

27:21

exactly the view from above. Wow.

27:23

Okay. So it wasn't just for a few seconds.

27:26

So I did it seems to be the

27:28

photographic memory for a few seconds which is

27:30

kind of normal in kids and the photographic

27:32

is in adults and he's the only case

27:35

born on a blue day guy that I've

27:37

heard of who has it. Is that kind

27:39

of helping you there Dr Harper? It

27:42

has. So

27:44

photographic memory is not so much

27:46

proven? Well he's

27:49

the only case on... People say, oh I've

27:51

got a photographic memory and then

27:53

you say, okay here's a phone book and then you

27:55

show them... People don't know what a phone

27:57

book is anymore. It's a bit of paper that

27:59

has... numbers in a... okay, right. And you

28:01

say, okay, in the right-hand column

28:03

what was the one that sits from the

28:05

top, right? We can't do that. Yeah. Right,

28:07

okay. But if you had a photographic memory,

28:10

you could. And I was

28:12

suspecting that Born on a Blue Day Dude

28:14

could as well. Interesting. Thanks,

28:16

Harper. Thank you. Actually, and you

28:18

said this is something that you'd been looking into. What

28:20

kind of sparked that interest? Um,

28:24

funnily enough, I was watching Criminal

28:27

Minds and there's

28:29

someone on there, Spencer Reed, and

28:31

he is

28:33

considered a genius in the show. And somebody said

28:35

to him, oh, well, you've got a photographic memory.

28:38

It's kind of like a hack. And he's like,

28:40

no, I have an idiotic memory. They're different. And

28:42

I was like, oh, interesting. So that sort

28:44

of sparked that funnily enough. I

28:46

love that. Wow. All right. Well, if you have a

28:49

question that was sparked from a TV show or a

28:51

movie, let us know. 0439 757 555. We've

28:56

got Dave in Tassie here.

28:58

Dave, what's your question? Good

29:00

day, doctors. My question is, if

29:03

we're allowed to believe that nothing can move faster than

29:05

the speed of light, if that's what

29:08

we're allowed to believe, then does that

29:10

change our understanding of physics

29:13

on the grand scale when we accept that

29:15

our universe is moving faster than the speed

29:17

of light, what carries matter with it?

29:20

Ah, no, that's built

29:22

in. That's okay. So nothing

29:26

can move across the fabric

29:28

of space time, which

29:30

is three dimensions of space and one

29:32

of time. Nothing can move across

29:35

that fabric at the speed

29:37

of light. If it has any mass,

29:39

if it has no mass, it can travel at the

29:42

speed of light. The photon has no mass. Nothing

29:45

can travel faster than light according

29:47

to our understanding today. And

29:49

it kind of fits in with the old,

29:52

where are the aliens? Because if

29:55

we could travel at the speed of light, the

29:57

neighborhood would be full of aliens, you know, sort of

30:00

coming to look at our primitive

30:02

civilization. So think about it as dough

30:04

with raisins and you chuck it

30:07

in the oven and the

30:09

dough rises and the raisins move

30:12

with the dough and they move

30:14

apart. They're not traveling through the

30:16

dough. They're moving with the dough. So

30:19

in the early days of the universe, like

30:22

of the order of billionths of a

30:24

second after it formed, it did expand

30:27

at many thousands of times faster than the

30:29

speed of life. But that was

30:31

a fabric of the universe. So it can do... and

30:35

when I say the fabric of the universe, it turns out that

30:37

there's not just the three dimensions of space but another seven or

30:39

eight. So we don't know where they

30:42

are and we'll probably solve that mystery sometime

30:44

this century. So I'm not

30:46

deep enough to able to answer that

30:48

but there is a fact that there are no

30:50

aliens around visiting us with

30:53

all his extra knowledge and wanting to sell it

30:55

to us for something money. I

30:57

don't know. It's too hard. I'm

30:59

giving up. We need the clever

31:01

people in physics to answer that

31:04

one. Well who could we get on? Oh

31:07

we have various clever

31:09

people. We had Lord Greyson and we

31:11

had Groyd. We could get a few

31:13

of these clever people back on again.

31:15

Yeah maybe we do a physics episode. Dave, leave

31:17

it with us okay? Awesome. Ruben

31:20

in Brisbane, what's your question? Morning

31:23

doctors. I was just wondering if certain

31:26

foods and certain liquids that we

31:28

consume can change the taste

31:32

of our bodily fluids that we

31:34

passed others. Certainly.

31:38

Okay so apparently

31:41

nutmeg will come through as a bit of

31:43

a flavor in the sperm and

31:45

it seems to come through the pathway.

31:49

Sophagus, stomach, small intestine,

31:52

liver, then is a bloodstream and

31:54

it's not swept up by the

31:56

kidneys or it is but enough

31:58

gets through into the into

32:00

the seminal fluid. So apparently nutmeg makes its

32:02

way through, that's the only one I've heard

32:05

of. Or maybe caraway but mainly nutmeg. And

32:07

is that pleasant or not? I don't know,

32:10

it was just mentioned as a taste if you like

32:12

nutmeg is probably pleasant. What about the classic

32:14

pineapple that people mention? Oh I've never

32:16

heard of pineapple. So there's a second

32:18

option. So this would require some on-ground

32:20

testing and of course you'd have to

32:22

have controls as well. It looks like

32:24

it'd be a difficult experiment to get

32:26

past the ethics committee. I'm allergic to

32:29

pineapple so hence why the question was

32:31

coming through. Right, okay nutmeg is all

32:33

I can think of. If anybody's got

32:35

any suggestions, what's the magic number they

32:37

should deliver for? Text me 043975 at

32:39

7555. We've got Leela in Sydney. Leela

32:43

what do you want to know? Hey

32:46

doctors, I was wondering why

32:48

do all upshops smell the

32:51

same. How

32:53

would you describe the smell Leela?

32:56

Oh it's so distinct. A little

33:00

bit old and musty. Musty,

33:03

musty liver? Not

33:05

necessarily, you get the same smell in

33:08

vintage stores secondhand. Such

33:10

a distinct upshop

33:12

smell. And the thing is Leela

33:14

you bring it home with you as well. I got a

33:17

beautiful dress from a vintage shop in Japan. So

33:19

you think about how that dress has

33:22

traveled across the globe, come to Australia,

33:24

I've gotten out of my suitcase and

33:26

that was last October. It still smells

33:28

like that and it's starting to almost

33:30

transfer to the clothes next to it

33:33

in my wardrobe. I've tried soaking it

33:35

in vinegar, in you know like a

33:37

bicarb soda or you know but it

33:39

just, it won't go.

33:41

Just for out of curiosity,

33:44

are the clothes put through a

33:46

wash cycle before they go out

33:48

on, you know to the

33:50

general public or if you've got fancy stuff

33:52

that needs dry cleaning I guess they wouldn't do that.

33:55

Surely, Leela what do you reckon? I don't

33:57

think they wash them before they go out on the floor.

33:59

We which is why you always wash them when you

34:01

get them after you purchase them. Okay. So firstly,

34:03

you've got the smells of that person's body

34:06

odor and that I think would decay away

34:08

in time. Then you've got the opportunity for

34:10

fungi to grow on there giving and the

34:13

common thing I was waiting to hear you

34:15

say was musty and you did say it.

34:17

So musty is the typical smell that I

34:19

get when I come into an op shop.

34:22

So I'm guessing that as well. And

34:25

then I'm guessing chemical smells

34:27

from the clothes next to them. But your

34:30

what do you call it?

34:32

Anecdotal evidence. Lucy,

34:34

the smell is transferring from this address to

34:36

other clothes in the cover. That makes perfect

34:38

sense because the molecules are traveling through the

34:40

air and slowly diffusing across. How

34:42

do you get rid of it? I'm thinking you

34:45

have to go more military industrial than vinegar and

34:47

sodium bi-carb. Go to dry cleaning and then you

34:49

might have to go to the dry cleaning specialist

34:51

who got super nasty chemicals that

34:53

can remove everything but they might damage

34:55

your clothes. Yeah, damn. Darn. But recycling

34:57

clothes is good because a lot of

34:59

them get thrown away and wasted. Parry

35:02

is terrible. We've had people on

35:04

this show talking about that. Totally. Upcycle.

35:06

Upcycle. Thanks, Leila. Thank you for bringing

35:08

to our attention, Dr Leila. We've got

35:10

Kayla in Melbourne here. Kayla, you've

35:12

got a question about space. Hello,

35:16

doctors. Hello,

35:19

Dr Cole. My question

35:21

is if there's

35:23

so much space junk in space

35:26

with the satellite,

35:30

why can't I see them in any

35:32

space photos or videos? What does that

35:34

mean for Earth in many, many years

35:37

to come having so much space

35:39

junk? The first

35:41

reason you can't see them is that

35:43

they're normally pretty small. Have you seen

35:45

the International Space Station? Yeah.

35:48

Okay, so it's big. That thing is huge.

35:50

100 metres by 20 metres

35:52

by 50 metres and you can

35:54

go online and you can find when it's going

35:56

to fly over you and you can be in

35:59

a city full of The street lights and

36:01

you can say oh hey on the you

36:03

business was a i was gonna come over

36:05

and about three minutes and yes or and

36:07

you can see it with a sudden he's

36:10

a hundred made His boss is T by

36:12

Twitty is very different from something that size

36:14

of a senior now and so you have

36:16

space junk smaller than a tiny tiny tiny

36:18

slice of pie which can has in the

36:21

past punched a hole through forces as a

36:23

sequence of the glass on the space shuttle

36:25

so most of it is small stuff and

36:27

will release use it as big stuff is

36:30

arrested. Three houses in most cases cause as

36:32

really small and also busy. The best seven

36:34

killed is a second. Law. That

36:36

space junk have an impact. In. Oh yes

36:38

36:42

up Kistler Syndromes Those of David Kiss

36:48

the When yeah that was too much

36:51

space jugs and what good is based

36:53

on his no one's generating ten lumps

36:55

which generates a hundred love to raise

36:57

the thousands and basically the risk which

36:59

we will see a wave way from

37:01

as above it is that low is

37:03

over to become uninhabitable of by our
