We’ve made it to the final hour. To bring things to a close, Rembert is joined by creative director and crystal artist Kerin Rose and FiveThirtyEight producer Jody Avirgan. They discuss all-nighters, the importance of sleep, and the odor of all-day podcasting.

Rembert Browne is hosting a 24-hour podcast marathon to raise money for his former youth tennis camp, Coach Wink's NJTL, in Atlanta to attend the US Open. You can donate to the cause at advantagekids.co/donate
