Oblivion: that wasn't hilarious
Oblivion: it was brilliantly complex though
Oblivion: hands down man

I free run myself, I do it most of the time when I'm not on the PC. I think its the best exercise you can get. :o But it can involve some pain, I once flipped off a wall but didn't flip, broke mu right arm in 3 places, luckily I'm left handed.
