And I think most people think that that's a good decision.

That's an example of we have made a societal norm that says...

It's unacceptable for a 14-year-old girl to be reproducing, certainly at the hands of an older man.

So if she gets pregnant from her 14-year-old boyfriend, that's a different discussion and we can help them both out.

Well, in this country anyway.

My point of this story is we've made a decision that this is no longer acceptable, just as we've made a decision that a husband can't rape his wife.

We have just decided that maybe that was cool 200 years ago.

It's not cool today.

So to play the other side of some of these arguments, is there someone watching us who's saying, Peter, Carol, you guys are talking about all this aggression stuff, but we're humans living in the 21st century.

We have to change.

We have to evolve as a species.

Is there a case to be made that men should be less aggressive because all of these evolutionary reasons that you described aren't as necessary?

Women and men are going to live through their reproductive lives.

We don't have this urgency.

We don't need this competition.

Again, I'm not saying I agree with that or anything, but I'm just saying like there's a steel man for the other side of this, just as in those extreme examples of we don't have sex with 14-year-olds and we don't rape our wives.

Well, it's interesting.

Food is a really tough one, isn't it?

It can be done.

It just takes a ton of willpower.
