What an incredible legacy for Joan Benoit Samuelson. Yesterday she finished the Boston Marathon on the 40th anniversary of her best run in 1979.  As someone who is not that far off 61 and who would only run that far is someone was chasing me with a gun I really appreciated her son's admission mixed in with his pride.  At 29 he says he can't keep up with her so maybe the rest of us don't have to feel so bad either.  Still it does prove if you want to stay in shape and health age is mind over matter.  Congratulations Joan, you are amazing.
