I do 12 100 yard sprints ( really just a slow jog ), and 8 sets of 40 push-ups, three times a week.
The post exercise endorphin rush is a great bonus.
I’m almost 70 years old chronologically. But, I feel like I’m 29.
I find the momentary feeling of well being and the peace and quiet from a very modest 45 minute times three a week cardio/strength program to be benefical. I am not really improving my health but maybe slowing its decline.
You must've had one heck of a recent political epiphany to have waited so long.
OTOH, you may actually be an FR veteran. Here for twenty years, left, then returned with a new screen name so no one would recognize you.
So not only would you be a "very new oldie", you'd also be a "very old newbie".
(Eight sets of forty, huh?)
