Young at Heart

Many thanks to brother-in-law JM for this one. Click HERE to see a video of a 90-year old couple who stumble on a piano in the lobby of the Mayo Clinic and start to play a duet. I hope that at 90 I will be dancing, running, sailing and practicing yoga! But not playing a duet - I don't think I remember how to play chopsticks!
