What might nighttime impulsiveness look like for us if we drink too much coffee late into the evening?

negative in a way that you don't want to fly around when you do not you you're not supposed to now you mentioned the night shift workers where it might actually be useful because it keeps them awake alert better to focus all that exactly but there's some jobs where impulsiveness would be a terrible thing like maybe a surgeon an air traffic controller would you recommend for those folks maybe not drinking too much coffee late into the night

Now, when I hear about experiments with fruit flies, I kind of naturally wonder how much of the results would translate into human behavior.

How do we make that leap?

How do we say, OK, we've observed it in fruit flies.

We also suspect it might happen in humans, too.

Now, back to the research and looking at it at a high level.

Caffeine, it's been a part of human culture for, I don't know, in some cultures, thousands of years and other centuries.

Do you now think twice before having that late night coffee before you have to get something done?

Would you recommend other people think twice and really think about what they're doing, making sure it's not driving or something where impulsivity would be a bad idea?

All right.

Maybe I'll be a research subject.

Well, Kyung-An Han is a biology professor at the University of Texas at El Paso.

Kay, I've enjoyed the chat.

Thanks for being on the show.

Firefighter, Leo.

I need you to make your own risk assessment.

We're going in.

Deep in the woods behind you, there's a wildfire.

It's off.
