My grandfather had his GB out in the 50's. Just died a few years ago at the age of 96. Drove his car until his last 6 months of life. You just never know.
PS Had my GB out 2/27 - emergency surgery (open and 4 hours long). It was badly infected and had a large stone that was almost as large as the GB. Only missed 2 weeks of work (bugged the DR until he said if I felt like it go back to work). My 2nd week back to work. Still a little slow, but getting stronger every day!
