Mental speed is high until age sixty

"he need for reading glasses varies quite a bit and is probably a good yardstick. Some people get their first reading glasses at 40 other’s 60, that’s a huge range." I'd like to meet someone at 60 who hasn't aged. They might not need reading glasses but pretty sure they will otherwise be old, with gray or balding hair, bad knees, etc.

My point was everyone ages, but young 60 and old 40 can look a lot alike.

Balding isn’t universal, a friend of mine is 70 and looks 50 with a full head of hair that not full grey, it’s kind of freaky. He’s still working construction and carrying heavy loads etc. Meanwhile I started going grey at 20.

I agree 40 and 60 can look similar but from what I've seen, being young at 60 is due more to taking care of yourself than genetics.

At least hair loss and going grey is genetic. I am sure being overweight etc plays a major role, but I wouldn’t rule out a genetic component to most signs of aging.

your use of "yardstick" (a measuring tool) confused people about what correlations you intended.
