Thanks for the advice on exercise, C R. This is not my first trip to the "Fat Farm, what I call it" I have attended there in the past. Yes, exercise can be unprofitable if over taxing the body happens. I do Cardio workout one day then on the second day I do weight lifting and some cardio for warm up. All weight lifters say you body needs a day to recover from serious weight training, or one really does more harm than good.
I started back on the stationary bike, and tredmill, which I have at home, about a month ago. I have already noticed improvement on ease of getting up from a seated position. My Dr suggested me getting on weight lifting, prior to surgery, to improve knee strength, so I am taking that advice to heart. He says it should help my recovery from the knee surgery.
I am hoping to be able to go to the "Cowboy Way Festivle" held at Gene Autry, Oklahoma in mid May. They are having a Cast reunion of "The Virginian" series and some of the "Gunsmoke" actors. Went last year and seen "The Virginian," James Drury, Betsy, "Roberta Shore, and Steve, "Gary Clark. Was interesting. A big change from TV today. Who cares for the stuff (Reality) they have on today? Any ways, we will see. That is my goal.
I do recognize my "somewhat" compromised health, when it comes to being prepared to defend myself. If one can't move he is a sitting duck, IMO. That really diminishes one's effectiveness. My desire it to get back some of my lost movement, due to great knee pain, although I know not all will be restored. Man just can not make them like God does.
