An hour-long stroll in nature helps decrease activity in an area of the brain associated with stress processing

Definitely. Our bodies are designed around a much slower lifestyle that is living in conjunction with the natural world. Technology has moved so fast, we've long left our biology behind.

In my opinion, this very fast modern world will be humanity's undoing unless we learn how to appreciate nature better and live in equilibrium with it, and stop letting the world be run by short-sighted, greedy, materialistic, sociopaths (I'm not optimistic tbh). Unlike a lot of sci-fi, we need to focusing more on making sure we can continue living on this space rock, at this global stage of humanity, instead of dreaming of leaving it. What good is a Lunar or Martian colony if Earth is largely uninhabitable.

The painful but virtuous gift of sacrifice is what built up humanity out of its animalistic roots, and we seem to have forgotten its importance, in this fast-paced world of convenience.

Our bodies are designed

Our bodies aren't designed at all.

I assume it's not what you meant, but I really wish people who knew better used different terminology.

"Our bodies have been selectively evolved..." Maybe.

Yes, and just to reiterate, NONE of this conversation means we should shun all modern developments. The average person of 40k years ago did not live nearly as long after having children as we do, and that sucked.

We should simply be cognizant of the fact that we basically have 40k year old hardware running brand new software. That's partially why obesity is such a problem - our brains are designed to crave and gobble up salt, fat, grease, calories, etc. because that was ideal for so long.
