Just got out of the hospital last week.Had a right hip replacement done.Wont be crawling under any car for several months although working uprite will be good in a couple of months.Had my left knee replaced in November.Amazing what they can do now with these new wonder materials they have come up with.30 years ago I guess I would have been living with worn out joints the rest of my life.I rebuild my old car with some reproduction parts and my surgeon rebuilds me the same way.Been a long winter but come spring I will be all set to go.
