But there is.

There's something almost magical that you can be in a crowded room of people and there's someone that you feel really attracted to.

You feel drawn across the room.

Researchers have argued about what that is.

Can you really smell them from that far?

Is it something about their physical traits?

It's probably a mix of things.

It could be their style, how they're dressed.

It could be how they move their hair and their body.

It could be their facial features.

could be who they're with.

We also engage in what we call mate copying behavior.

So guppies do this, for instance.

Female guppies will look at older females, sometimes even their mothers, and see what males they're mating with.

And then the younger females will go mate with those same males.

Well, humans do something a little bit different, but in similar, we do look at who you are surrounded by.

If you're with attractive others, we tend to view you more attractively.

So there's all this that's going on too.

So you might think you're just looking at that one person across the room and you feel that chemistry.

But in fact, the brain is taking in information about who is that person?
