Huh. I have worked 40 years and raised a bunch of kids, not as much leisure but holding up fine. I do work at a sports company though, people take long lunches to go for a run and we have a gym too. So there is both the flexibility and resources to stay fit. Really nice perk.
Honestly don't mind working now, it was harder when I was younger with kids at home and not as much seniority at work.

Insufficient plastic bags, they can't survive a direct hit like that. They do work for regular showers, to keep the incidental splashes off.
