I've noticed this as well. I think it's a pretty good analogy. That realization came after being homeschooled for a few years as a teen. In my case, this meant less opportunity to socialize. After returning to public school, my "level of fitness" increased pretty quickly to way it's consider normal/healthy. The pandemic had similar effects that required a bit of effort to correct.

Just like physical fitness, some need more/less exercise to stay fit. There will also be different preferences for were that exercise is done (at or outside the office).
