I wonder if employers will be more receptive to regular breaks for knowledge workers who are mostly sedentary. One befits of working from home before being mandated back to the office was being able to go on a walk during lunch and less-critical meetings.

That sounds pedantic. It's not like people get older and decide to be less active. Your muscles atrophy, and it's not as easy.

Your muscles atrophy if you don't use them. A 60 year old power lifter is stronger than a 30 year old who never lifts. On average people lose around 5% of their muscle mass per decade after 30; someone with twice as much muscle mass at 30 is still going to have more muscle mass at 60 than the person who started at 30 with half as much muscle mass.

Except for really old age, they mostly atrophy because of sedentarism. Even then, I've seen excellent climbers and alpinists past 70. Keep moving and your body will keep working.

You see this often with middle class city people in their late 20s and 30s.

You go from being athletic in high school and walking all day in college to suddenly being in your prime dating age, regularly out eating and drinking with friends or dates, hitting 2-3 cocktails a few nights a week. You start investing more into your ultra-sedentary career, which you drive to, which constantly requires more of your time to get that next promotion. You are unable to have healthy home cooking, instead replacing it with restaurant work lunches and happy hours with your coworkers.

In addition, as you make more money, that enables even more convenience. Amazon delivers you products, no need to leave the house. Instacart delivers you groceries, no need to even go to the corner store. Doordash always at the ready to indulge every craving. Uber will happily save you every step you choose not to take.

All of that quickly adds up way before you even hit your 40s, and many will claim that it's their metabolism, when in reality it's 100% a result of a dramatic lifestyle change.

I’m at the point where my peers complain about getting older.[1] And I’ve started wondering how much of that is really about age and how much is the cumulative effects of “lifestyle”. I mean if you sit in a chair for ten years for 12 hours a day you’ve probably become “too old” for doing cartwheels. But it could be reversed, maybe.

[1] Am I 25 or 50? Impossible to say in this climate of complaining.

The effect of atrophy, meaning non-use, is larger than the effect of aging, yes.
