spend a week in the forest first finding a decent location, building your own shelter, gathering water, building fires, tracking animals, imagine having to contribute enough labor to help substantiate a family and possible a tribe and also being somewhat nomadic and having to do this often, long walks/hikes/hunts, taking down shelter, rebuilding shelter, carrying most of it with you, carrying water, long hunts....you will understand what you body is meant to do and how strong cavemen were to survive and flourish in nature. nature is huge and all the things we use from it are large and unwieldy, without the use of machine nature is a big heavy humbling creature...we are so disassociated with this now it is hard to give proper thought to where everything we have comes from natural resources, the labor of our ancestors (humans, animals, plants....all of those that have come before). our whole day was physical labor(exercise)
The only reason nature is large & unwieldy, is because we've become large & unwieldy, I dont believe we were ever meant to become sentient in the sense we are now, we were meant to be animals
If you read Lloyd Pyes work, he points out we've been lied to, cavemen looked nothing like us, they were essentially real animals & lived in total harmony with nature, as easily & comfortably as any gorilla or chimpanzee, they probably used sticks & stones in the same way chimps & monkeys use sticks today
They had natural insulation in the same vein as any dog or animal, could survive plenty of cold & find shelter if they wanted to, just like any animal
Whether theyre linked to us or not is highly debatable
We were meant to be animals, something changed all that & it sure as hell wasnt evolution ...
True sentiency is a persons imagination or dream states, the freedom of infinite action & an infinite number of realities, the same sentiency all animals use & the environment around us uses, our conciousness doesnt have the complexity to understand the world around it, filtering the world around it to a level of understanding it can understand, where animals seem unsentient & our environment unsentient & uncommunicable
This is why when babies are born, they loose 90% of their braincells, theyre forced from a dream state of infinite possibilities to a reality of a mass induced hallucinated belief in 3 dimensions
The human body is basically designed to work strenously in short bursts of upto 15-20 minutes, before it incurs heart damage
It can walk in leisure or in step infinitely, humans have always been designed to walk using gait for long distance walking over hundreds of miles, none stop safely, which many people in places like ethiopia still do to this day
