Thanks for your detailed reply! I have been attempting to incorporate more routine in my life, but I hadn't considered the why, really. The concept of reducing cognitive load makes sense, and I agree that "having to remember to do stuff sucks" 100%.

I'm curious about what optimizations you are making that reduce your need for sleep (as someone with lots of things they want to do and not enough time in the day to do them all). If you wouldn't mind briefly sharing I'd be much obliged.

A small percentage of the population uses the majority of the health-care. You would have died back then, but most of us would have been fine.

A fair amount of the world has no "need" for heating or air conditioning. Mediterranean climates and all of Latin America qualify here, as does much of Southeast Asia and the Pacific Islands.

In fact, the only place where HVAC would be a "need" would be super cold climates, or super hot climates. Everything else is tolerable, just not comfortable. Plenty of places are hot, but people lived there just fine before we had electricity or any fancy cooling tech.
