Good Luck with the surgery and your recovery Michael. Surgery is in the doctor's and God's hands. The recovery issues are principally in yours. The first week after surgery are "can we turn up the morphine any?", and ya feel like you've been run over by a tractor. The second week is "these things seem to be workin' but gosh it hurts". The third week after surgery, there seems to be an uptick in your outlook on life. Forth week, life is worth living after all. The sixth week, while left alone at the house, I decided that my eve troughs needed cleaning out, so I pulled out the ladder, climbed up 12-feet and cleaned out the eves. I did catch h--- for that, but that is the transition one can go through. I threw the pain pills away during the fourth week. Now, 5 years after the fact, I don't even think about having metal/poly knees, and 6 months of the year, I still climb 20 steps in a ship probably nothing less than twenty-five times a day. I'm sure, you will do well..........
