I don't know if trees were my ancestors, or how to talk to trees, or if junk DNA is our instinctual programming, but beyond that, this session was pure win. Perhaps these were metaphorical, I don't know.
He had me at the social aspects, at how school was designed to keep kids busy while their parents would be exploited with work, and how our creativity is suppressed by schooling and corporate work, where obeying is far more important.
I totally agree with his "It's natural to have the urge to..." and how modern life has trained us to turn off of all of these, and that we're dangerously out of touch with our primal natural urges, drives, and instincts. "Rise with the sun and set with the sun."
We've discussed the artificial lights and their effects on us in many questions here at PH, but of course it doesn't hurt to have those pointed out again.
The coffee and green tea thing struck a chord of realization with me, as I tend to be a fiend with these two.
"In our primal environment, we had to live by the laws of and dictates of nature. For all creatures in the wild, there's a survival code and a need to live in accordance with that code, is the urge, simply to live or die if you're out of that code, you become food for some other creature." Pure gold.
Of course the environment our genome and epigenome was adapted to no longer exists, so it's difficult for us to return to that balance, and we should listen to our bodies, and simply as much as we can in our lives.
"Stress is trying to do too many things at once, be too many places at once, or be too many people at once."
I want to resist the urge to copy more quotes into this answer, or the slide points, but clearly, this, to me is a "must watch" session, it's pure gold!
