No it does not work that way. arthritis kicks in and your hands do not grip like they use too and your legs tend to collapse when using stairs. you will need to be tough to get old. Old age is not for the week.

Part of me is hoping I don't get particularly old. I was diagnosed with OA about three years ago and was told to avoid high-impact activities and wear braces. I'll eventually end up requiring joint replacements but am hoping to put it off until we have cybernetic enhancements perfected

And hopefully I can get Open Source cybernetics so I can hack them. Because I would try anyway...

Good on you. I had a replacement knee put in and have not been free of pain since. put it off ass long as you can.
