Hi,
I turned 71 this year; my wife is a mere 66 and our best dive buddies are a couple who are 74 and 70. We consistently find ourselves the oldest divers on most boats. We still do shore dives so we can be the youngest on a dive--since we are normally the only divers!
All that said, we consider ourselves good divers: last week we did 6 dives and had bottom times of ca. 1 hour and 20 minutes at 65'. Not bad for OF's. In fact, we usually have the best bottom times on most dives since we tend to be the most relaxed divers.
So, guys, hang in there and keep enjoying the "wet"!

Good for you! We're only 60 yo so I hope I'm still going strong when I grow up.
