If you look at a lot of competitive athletes and bodybuilders, they tend to be pretty broken in their old age. E.g. Ronnie Coleman - former Mr. Olympia - could barely walk after tons of spinal and back surgeries.
Maybe you have the bone density - but if you are immobile with tons of joint and arthritis issues, it probably will not help.
