hi Meraviglioso, wow, what a great system....doctor, physical therapy, highly qualified trainer. don't know that i've seen that in the US. Sounds like a brilliant idea.
As far as rewarding myself, got my eye on a road bicycle. I've got some guys who do a lot of biking who will let me know what i should purchase. I will put my trust in them as I know nothing. Low impact on my knees, but will allow me to try to get into cardiovascular condition at my own pace.
