Not having a job for 2 years and not being very physically active in that time I lost about 20 pounds of muscle and replaced it with about 20 pounds of fat. Don't think what I sit on has much to do with it as much as just being a lazy fuck in general.
I was using the couch vs computer chair term loosely, just wondering what people think about the different "kinds" of people. Not so much the different sitting surfaces. I'm more likely to pass out on a couch while aimlessly playing skate on PS3 for hours.
