Well said Lizad,
Sure, I know guys in their 60's who could kick out the miles and bury me when I was in my 40's, but that is an exception.
The same with mental acuity, there will be a few who are dedicated enough to overcome age related slowdown simply because they realize they aren't at the top of their game anymore. But the vast majority are relying on past experience and belief that any future decision will be handled as it was in the past.
PS Hornet, I retired at 56 with my bucket full. If you seem to think you have the pull to order a urine test for me, come on over, I'll pee on your hand!
