Huh. I live in the Land of Golf, but I've never played. But the guy who lived in my apartment before me left behind a set of clubs. Why are you suddenly playing gold? Want some clubs?
He would play many rounds with 70 year olds when he was in his late 80s, they would ask his age, he would never tell them and told them to guess. They would toss around low numbers near their age and he would just say "About there". He would not let them know he was 10-15 years older them many of them and could keep up with no issue.
