haha yes, i took the lift up with a guy last year, asked me if i could do helicopter spins.  I replied, you bet, do you still hit up the park?  He said, he just turned 80 and can still ski down the hill with one ski over his head.  i saw him a few runs later, and sure enough he was skiing down the hill with one ski over his head.  I was pretty amazed at the time.
