0:00.0	Hi, you're about to get smarter in just a few minutes with Curiosity Daily from
0:04.8	Curiosity.com. I'm Cody Goff. And I'm Ashley Hamer. Today you learn about why you
0:09.5	eat differently when you're stressed, how humpback whales use bubble nets to catch fish and
0:14.1	the surprising genetic reason why females outlive males.
0:18.0	That's satisfy some curiosity.
0:20.0	We eat differently when we're stressed and you're about to learn why.
0:24.0	We figured now might be a good time to talk about this since the coronavirus pandemic has turned life as we know it upside down.
0:30.0	And let's face it, your eating habits are probably among the many things about daily living that have dramatically changed.
0:37.5	Maybe you're snacking all day, accidentally devouring the groceries that were supposed to last another week, or maybe you're hardly eating at all.

1:08.8	It's why you might feel sick to your stomach before an important exam or a big performance or a live stream press briefing.
1:15.0	But the longer the stress lasts, the more of your body produces another stress hormone called cortisol.
1:20.0	Research suggests that high cortisol levels over the long term can mess with
1:24.8	levels of metabolic hormones like insulin and lepton, which can make your hunger
1:29.0	signals go out of whack. At the same time it may knock your brain's reward system off balance, which makes fatty,
1:35.4	sugary foods even more desirable.
