Aging is a nasty thing ugh, the way your bones get weak and your spine curls and you see old people hunched looking down at the ground when they walk

But I really think you're underestimating how active even the average 70 year old retiree can be.
Some people at 70 are in great health, some not so much.
Granted, both take focus and long term discipline which people who lack both chalk up to luck.
