I came here to say this. I'm an urban professional in my early 30's. I've studied Muay Thai for several years and have even fought in amateur fights quite a few times and every time I go to the weigh-ins I feel completely out of place. I'm just a nerdy guy in glasses who happens to love martial arts. Many of the fighters at these events are all tatted up (nothing wrong with that, of course, I have a couple tattoos myself, but these guys have neck/face tattoos), wearing their Tap Out shirts, really looking to prove something (and not in a good way). The culture has gotten MUCH better in the last few years, but there is a slight resurgence with these new UFC franchise gyms popping up.
