You want to be able to keep physically independent as an old man up to at least age 90 and stave off a bunch of crippling conditions that make life miserable?
For the health that's another part. My paternal grandpa lived to 94 (died 2014). Until he was 93 he walked 3 miles a day, up and down hills. He lived near a Saltwater State Park and walked there every day rain or shine. He also did calisthenics including push ups for a long time, I think he stopped doing the push-ups sometimes in his early/mid 80s though. But I remember when he took me and my brother to Sun Lakes in Eastern Washington, he led my brother and I in doing 25 push ups in the morning as part of his routine, which I could barely do. (sorry, went on my own old man tangent then). He had a series of strokes at 93 and died at 94. But he was active and totally cognizant of his surroundings until his first stroke then it was a quick loss of function.
My maternal grandmother had lymphedema, was obese and had type 2 diabetes. She stopped being totally mobile in her late 50s. She was partially mobile until she was about 75 and died at about 85? Starting when I was about 10 she would have me drive her the 300 yards or so to her youngest son's, my uncle, house.
