I'm about to turn 67 and I'm riding better than I have in 10 yrs. When I think about age, which isn't often, I just tell myself to be the best (fill in number) year old I can. Thanks to weather riding has been more sporadic than years gone by but it is what it is. I think if you just focus on each ride and enjoy it for what it is rather than focusing on what it's not you will find life easier.
