81 riding a bike. Good for him. He kept his health till the end.
Just got off the phone with my mom who's Spending her first Mother's Day without my dad who passed in February at 88. He jogged on his treadmill till he was 84 or 85. He slipped and fell doing some yard work, and while he didn't break his hip he bruised it pretty well and laid him up. It seems like the sudden cessation of his physical activities led to the noticeable onset of dementia and he took a steep decline over the past year before passing.
