I'll start. I love the strength and general physical capability that we have, it feels great and I'm proud of it. I also really love the feeling of camaraderie and brotherhood that can exist between guys. It's a kind of deep, abiding, silently knowing feeling you get from your buddies of "I got your back, bro" that's difficult to put to words, but it feels so right and good.

EDIT: Wow, looks like the experiment was a success! Sweet!

EDIT 2: Hey just wanted to stop in again and say how awesome it was to read all the responses here, especially the interesting / thoughtful ones; this is a really cool place. Thanks bros.
