I've been tinkering about what could be the secret ingredient that makes males attractive to women, and I think that it's not one's physical appearance per se- it's about looking capable.

This is not to say that the genes, and thus, the looks aren't important, but of what use is being handsome if one can't help themselves?

This begs the question, however, of what exactly makes one look capable in a non-verbal way, with of course looking healthy and fit being a clear non-verbal signal that one's capable to some capacity (a sign of having endurance, perseverance, discipline and will), but what other "traits" are there?

I'd like to think that one's clothing and body language (the way one carries themselves) also plays an important role.

What's a way to improve on these two, and what other things can you think of?
