The only reason hunter gatherers didnt live long lives, was because they had malformed communities & no effective forms of communication, resulting in whats known as socially induced apoptis, cell death
Poor health didnt kill them, it was loneliness ... & no real communities or relationships to convince our biology, which is hard wired to survive in a community & through relationships, simply doesnt work in the face of a life time of solitude, or a life time of long spells away from loved ones
Longevity has very little to do with nutrition, apart from regeneration & healing, its well formed communities & the relationships we create, which give us the reason to live,
Its proving to our natural selection of cells, through complying with the natural social checks built into our cells, designed to weed out ppl who cant function in a community, or form healthy & long living relationships with the people around them, our very own cells start to kill themselves, if we cant communicate effectively in a community & relate to ppl
The MAJOR factor in modern longevity, is nobody is ever really alone, thanks to telephones, televison, the internet, we convince our socially hard wired cells to let us live longer
This is why hunter gatherers, & other older tribes & cities had such short life spans, fractioned communities with none functioning relationships & poor communication, induces socially induced cell apoptis
Our cells dont work, if we dont have relationships to use them & diversity afforded of complex communicative relationships
It's no coincidence, with the rise of the mechanical print & the invention of wireless & telephones, the mortality rates of people, living in isolated communities & poor functioning relationships, started to rise
The Diversity & complexity of communication, allows us to form more effective communities, & relationships, which convinces our socially hardwired cells, for working in tribes & packs, to stop dying
Our biological cells are hardwired to naturally weed out anyone who cant function in a tribe or a community, even if that person is in full health
If all our televisions, phones, internet, stopped functioning, millions of people, even if they were all on raw paleo diets, would start dying of socially induced cellular apoptis, because of the lack of diverse communication between hundreds of different communities & relationships they no longer have.
