I get that this is tongue in cheek, but seriously, some people are just waiting to die and seem to find joy in tracking how their body is breaking down vs doing something about it.
Body maintenance becomes more and more necessary as you get older. Use it or lose it.
Do strength training on the weakest parts of your body (hips, ankles, knees, shoulder, rotator cuffs, lower back, neck) and you will thank yourself decades later.
