All that is arbitrary.
I’m 65 and the only way I might be able to detect a difference between my riding now and 35 years ago would be to put a clock on it. OTOH, when I go to reunions of my school class, some people got old, some didn’t. When I was a kid, the idea of a man my age spending a couple of hours riding a bike uphill in order to shred the DH was unimaginable.
I don’t feel any different, and nothing in my body hurts after a ride.
My mum is 91, just renewed her driving licence, but with the price of fuel she prefers to walk to the market.
Who cares what you call it?
