above 50 years old and still programming

[TysonLPrice]

I know that some of you is more than 50 years old already and still programming, my worry is that, can we keep on doing it until we retire?

Samuel remained an active computer programmer long after age forced him to give up active research. His last work, continued until past the age of 85 involved modifying programs for printing in multiple type fonts on some of the Stanford Computer Science Department's computers. We believe he was the world's oldest active computer programmer. The computer he used tells us that he last logged into it on February 2, 1990. This was after Parkinson's disease stopped his active work.
