Our instincts want us to live how we were in tribal times.
Humans, as all living things, evolved and adapted to survive in their environment. Over hundreds of thousands of years we physically and mentally became perfectly suited to how we lived. In the scheme of things we lived for the longest period of time as tribal hunter gatherers. This is how we are evolved to live physically and mentally.
When we are born certain ways of behaving our already programmed into us, these are our instincts.
Since tribal living times the environment we live in has changed must faster than our speed of evolution can keep up with. We are not adapted to live alone. To suppress our feelings and bottle them up.
Evolution takes thousands of millions of years. Change is slow and happens via the survival of the fittest. The most successful humans survive, have more children to carry their genes on and spread those genes.
Evolution is a slow process. Over the last few hundred years the way humans live has changed far faster than evolution could keep up with. We are living longer more easily on a physical. Mentally and socially not any happier.
The lives we are evolved to live
This is they way our bodies and instincts are adapted for us to live.
We would have lived in extended family groups. Survival was tough so we would have all depended on each other to get buy. There would have been genuine support from all members of the group.
Diet:
Hunter and gatherers would most often eat vegetables, occasionally meat and fruit. The drive of hunger evolved to make us hunt or gather our food. Its a strong drive needed to push us to go far and seek food not open the fridge nearby.
Social lives:
We would have always had close friends and family around us. Wiser older people to advise. Multiple parental figures to love and care for us.
