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.
We raise our children to treat people the way they want to be treated and to share their toys with others.
That doesn't happen as adults though. Everyone has their own things and we need to be skeptical of certain people.
I don't force my children to share with others and our main rule is to not hurt your family.
