[upbeat music] Brains On Universe. You're listening to Brains On, where we're serious about being curious.
Molly Bloom· Host0:14
[upbeat music] Some things are simple and complex at the same time.
Maya· Guest0:19
Like getting dressed in the morning.
Molly Bloom· Host0:21
Yeah. You just need to put on clothes. Simple.

Molly Bloom· Host0:36

Maya· Guest0:38

Molly Bloom· Host0:41

Maya· Guest0:45
