One is the honest signal, or it's the kind of a handicap hypothesis, because you're holding yourself back whilst proving you can still do it.
I ran the marathon, you know, carrying a couple of weights.
You're obviously stronger than the guy who ran the marathon without.
Um, and so that's why it's an honest signal and it's why it's a handicap.
But the other one is what's called the sexy sons hypothesis.

There is,
