I'm a sofa spud myself. I like to watch TV and work/play on the computer. I can occasionally rouse myself to do the dishes and clean the bathroom, but for the most part I'm not physically active. I don't feel any particular loss because of it. Exercise hurts too much and I have no place to walk (I live on a steep hill and can't get up OR down it because of my knees). I wish I could swim, but that's out too as it costs money and I don't have reliable transportation anyway. So, a couch potato I am and a couch potato I will remain.
