The most important aspect of being Primal for me is rediscovering my own drives and thoughts as experienced by an animal on the earth. The nutrition and fitness thing is for me an effect and consequence of this, not the other way around; I was tired of identifying with this or that cause or group and wanted to be me, this genetic expression in this body. That made a lot of my behavior then seem insane and contrary to what I truly wanted.
That's because to cram us all into the grid that they built out of iron and oil and concrete, they have to break our mind (like with any domesticated animal) and make us stop identifying with ourselves and our own needs and appetites. We are made to feel puny, insignificant, powerless and alone but for inclusion in their game. So we identify with our captors and become sports fans and democrats and this or that class with this or that interest- our genetic demands for intense experiences and our need to be endure traumatic upheaval are made vicarious, so that instead of successfully fleeing predators, aiding friends, interacting with our ecology and protecting people, we are bathed in electronic media that simulates this for us.
Just enough to keep us healthy and sane enough to get to work tomorrow.
