I think about historical, 2-phase sleep a lot. One reason it will be difficult to restore natural sleep cycles is that life has become increasingly complex; we have exponentially more responsibilities than our ancestors had. In short, we are unlikely have a couple more hours to add to our sleep periods. |
I'm not really responsible for getting edible food, drinkable water, warmth, cover, shelter from the elements, protection from hostile animals or enemy humans.
I also don't have to actually make anything with my own hands.
So, yeah, indirectly I do some of these things by earning a salary, paying bills and buying stuff, but I not sure that the work I do day to day is much more complex or responsible than what an equivalent neolithic hunter gatherer would be doing.
I don't on a daily basis do things that could get me or my family members killed if I did them wrong.
Also a lot of what we consider primitive skills take a lot more art or technique than we appreciate. Flint tools look like they might take real skill do do well.
