Maybe a better question is; How many folks are willing and able to stay on past age 65?

I'm not sure that any official data has been gathered on that, but looking at part 91 (corporate) and 135 operations does any one have a good idea?

I've heard of and also run into a few guys who seem to be "fly til I die" types. Which I hope to do myself, but I'd like to give up flying *professionally* sometime before turing 65.
