With the possible exception of Alzheimer, senility or a physical impairment age seems to not be an issue. I just turned 60 am one of younger of the older group of racers. Some of the guys I go against are old enough to be my Grandfather.
I do see effects of age myself. I am not as quick as I once was, sometimes it takes me longer to remember a name or such. Everything else seems fine for the most part. I know there are things I used to do that cannot be done now.
I can still compete with Grandsons at video games. Not as easy to win now.
I can still be effective drag racing evidenced by winning one of the first pair of points races. Starting the year off with positive cash flow is nice after struggling last 2 years.
Driving/towing with RV is still no issue. Wife and I are both effective driving. I seriously doubt if either us could be considered a hazard to navigation. I expect we can continue for at least the next 10 years unless some health issue arises.
I do see plenty of all ages that should be walking. I guess drivers ed never told them no tailgating or running side by side. Defensive driving and proper spacing was one of the first things we learned, always have escape route.
