Losing parts is no fun, but I thank my lucky stars that I was born in an age where such surgery is possible. I would be long dead were it not for the ability of some doctor to fix my problem by removing or repairing one of my parts. I had major blockage in five major vessels of my heart, and went through quintuple coronary bypass, and that was 22 years ago and I am still going strong. After a punctured lung I ended up with a life threatening lung infection and during the surgery to remove 5 quarts of infected material out of my lung I "lost" about one third of that lung, and now 18 years later I am still doing OK. More recently, a CAT scan for a kidney stone showed a mass on my other kidney which turned out to be cancer, and that kidney had to be removed and right now I am fine with the one remaining kidney. And last of all, I have "lost" both knees, about 14 years ago, when I almost had to give up the ability to walk due to severe arthritis, but I walk just fine now with the artificial knees. So as you can see, I have lost a lot of parts and I'm still here on the green side of the grass. Don't get too discouraged at having to give up parts as long as you get to keep the rest of you still working. Stay alive even if you can't stay whole!
