So there will be a lot of side effects of having caffeine late at night, although there may be individual differences as well too.

I mean, you and I know that

the way that we behave is based on our experiences as well too, beyond genetic makeup.

So people who are highly resistant to the effect of caffeine, they may be okay because they've been doing it, body developed how to deal with it.

So it may be okay with them.

But for those who are new to caffeine,

Maybe it's not a really good idea for them to use too much caffeine at night because it really does interact with a lot of molecular components that are active in the brain at night.

And therefore, I think it could have a different way of controlling behavior than what we intended.

So maybe many of the audience think, oh, flies are kind of different than humans.

But we shall see in future how it does.

Maybe you could maybe test how it influenced you by drinking coffee at night and see how impossible it can become.

It was wonderful.

Thank you for having me.

Thank you for inviting me.

I'm excited to talk to you about our recent study on caffeine's effect on behavior.

Well, what do you mean by good?

I think good is really subjective.

I mean, if your goal is to stay awake to study finals, obviously it's a good idea to drink coffee whenever you need it.

But you just need to watch not to drive afterwards because you don't want to drive through yellow lights.

Oh, I suppose that's what- That would be impulsivity.
