0:00.0	Hey, it's Janice from WBD.
0:03.0	We're producing fresh apps for Curiosity Daily.
0:06.8	In the meantime, check this one out from last year.
0:10.1	Keep with the feed for more soon.
0:16.9	Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Discovery.
0:21.3	Time flies when you're learning super cool stuff. I'm Nate.
0:24.1	And I'm Callie. If you're dropping in for the first time, welcome to Curiosity, where we aim to
0:28.1	blow your mind by helping you to grow your mind. If you're a loyal listener, welcome back.
0:32.4	Today, you'll learn about how the bilingual brain might be better at multitasking, good news for women who are at risk
0:38.8	for morning sickness, and the strangely complex science behind cat purring.
0:44.0	Without further ado, let's satisfy some curiosity.
0:47.2	People who are bilingual, it turns out, might just be better at switching gears from one
