I'll be 75 in a month. Same as I've always been just less stamina even though I exercise daily in the form of 2 mile walks. Still drive to San Francisco from Orange County, a 400+ mile trip one way, 3 times a year to see my old Vietnam buddy. Oh and naps become your friend.
The one thing that has changed is I don't have the time or patience for extended family drama over stupid shit like Covid rules in their homes. I just don't go.
