TweetSame here, bro.
It happened to me back in late 2003 when I had knee injuries and was out from work for a year (minus a couple of months on light duty). All I did was sit at home on the computer (which is when I registered on about 30 boards) and watched TV. Crap food was basically all that I ate, since it was hard to walk and stand up to cook. After both knees were operated on, quite a bit accumulated on me. Along with the weight that I gained from powerlifting, my doctors felt that I was huuuuuuge.
