I am only 65 years old, but as my grandfather used to say “It’s not the miles you’ve gone, but the roads you driven.” Amen.
Your just a kid, 65 is the time life just starts right? (Or there abouts) The miles don't always count, my father lived life in the fast lane but he didn't settle down until he was in his 50's, no one thought he'd make it to 60 but here he is in his 70's now.
Funny how things work.
