Joe,
I know what it is like to not be able to run or do things like we used to. I used to play racquetball and got up as high as #4 in the rankings. Back then I could run for hours and had trouble keeping enough weight on me to not grow weak. Now I need to lose about 40 pounds and it is going to be hard to do as I can't even walk fast for more than about a block until that leg and hip are really hurting so bad I have to stop and sit down. At least if I stop eating that will save me some money.
