From personal experience, you start moving a bit differently, and not shy away from certain positions and ways of doing things. It's certainly nice, but it didn't change the way I interact with people or make different people attracted to me or anything like that. It's a bit of improvement, but learning the Bayes theorem was an order of magnitude more awesome, and reading up on syntax theory, physics, AI and bits of Marxism plus moving countries worked way better for getting people interested in me.
Of course this is anecdotal, but that's what I would expect from the experiment. Secondary confidence improvement would be expected, but that's thanks to awareness that you are more compliant with what Men's Health says you should look like, not inherent property of humans (see: places and times when fat people were seen as more attractive).
I find that it gives you a feeling of wellbeing that you can't get elsewhere. I don't mean that you can't feel good if you aren't strong. I mean the feeling of wellbeing that you get from it is unique and I haven't found it elsewhere.
Eh, I wouldn't relate it to squat strength, and it has diminishing returns. But biochemistry of the brain during exercise is fun stuff, and explains a lot of elation people have.
It's definitely related to squat strength. It makes me feel light of my feet, well balanced and generally younger than any other form of exercise that I've done.
