0:00.0	Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Discovery.
0:09.0	Time flies when you learn in super cool stuff.
0:11.0	I'm Nate.
0:12.0	And I'm Callie. If you're dropping in for the first time
0:13.9	welcome to curiosity where we aim to blow your mind by helping you to grow your mind.
0:17.4	If you're a loyal listener, welcome back. Today you'll learn about the 139 genes that set the human mind apart from our primate cousins,
0:25.7	a new gel that could change the game for those suffering from dry mouth, and why psychopaths
0:31.7	could be immune from the contagious yawn.
0:34.3	Without further ado, let's satisfy some curiosity.
