Sorry, Brian,...

....but I think you're being a little bit of a wimp and more than a little self-indulgent.  In your interview, you're asked what was the first thing you remember when you woke up after your TKR.  You answer that it was the surgeon standing over you telling you all went well, and he's going to go tell your wife.  Some of us peons have yet to have a follow-up visit with our surgeon, and won't until 5 months have passed since surgery.  And you remark upon your constant, ongoing physical rehabilitation, innocent of the fact that some are strictly limited by financial guidelines. Your doctor, you state, wouldn't let you leave the hospital until you had 90 degrees of bend in your knee.  Really?  Your surgeon actually tracks that?   You say you're able to fight through the pain by reading of the tremendous suffering of true American heroes, and are buoyed up by the knowledge you don't have cancer, or MS or other debilitating disease.  You announce that recovery takes strong motivation and that you are very strongly motivated.  Does that sound a little like bragging to you?  But then, your interview is watched by millions of people who are interested in the experience of and the outcome of your surgery, and who of us can even come close to that milestone?
