Well, so it's younger people, but we start out in this funny place where, like, there are teenage girls who are dating and boys...

Who are not, but they're like in the same class together.

And that is what starts to create this average age difference that from an early age, when girls start dating, they look older because they look around and they see what are essentially boys that who have not gone through puberty yet.

And so that essentially, we just kind of get used to dating folks of a particular age range in that way.

And it kind of carries forward.

This is kind of speculative, but it is an intriguing mystery why it is that women like younger guys a little bit more on dates, but they end up partnering up with men who are a little older.

I think we often think about testosterone as an individual difference, as something that differs between people, and of course it does.

It's something that changes quite a bit with age.

Average gender differences, too.

But what testosterone does to our relationships is a little funny because testosterone varies a lot within a person depending on what exactly they're going through in their life at the moment.

And one of the biggest contributors is are you single or not?

Because when people are single, they know it and their body seems to know it and they produce more testosterone.

And that testosterone is part of what we get a little bit of that edge, a little bit of that energy.

You want to go out and socialize and spend time with people.

When people get into a relationship, and especially if that relationship is a happy one, their testosterone tends to decline because they don't need that late night energy in the same way anymore.

So I think that's useful in that sense.

Testosterone, it's not a thing that's like gonna exactly make you more desirable.

It's something that's responding to your social context.

Now, this is all independent of like people like taking supplements and things like that.

Yeah, that's exactly what you see.
