Stevie, I can not tell you how much anxiety I had after the 57 days on the first deep water start. I did not know how it would feel, whether it would break somehow or twist and snap. Nothing but a smooth out and no feeling of stress or pain. It's been that way for over two years. One thing I can warn you on: while pulling off my dry suit and stepping on the suit pulling the new knee joint apart, I pulled too hard and the knee came out of its resting area. I was upset but just sat down and gently pushed it back into the socket. I will not ever pull the knee in this matter again. No harmful lasting damage was done. Then while talking to another knee replacement patient, he said he was not able to fly fish with waders. If you think about it, when your are in unstable bottom conditions, you are pulling your knee apart in the same matter. After two seasons of waterskiing and riding a road bicycle 5000 miles per year, my active life is back again.
