Maybe not great rocking and rolling for a one night stand, but great husbands.

We literally have it all.

We also have the widest range of paternal investment

And the more sexual.

So I have a podcast called Mating Matters.

And one episode is called The Trouble with Testosterone.

And I cite a lot of studies that show that higher testosterone men tend to cheat more, have less empathy and compassion, have trouble falling in love.

And yeah, get in bar fights.

They're the dudes, right?

So here's a really cool thing.

I love...

I love evolutionary psychology because it explains all of life to me.
