Compare the causes of death in midlife now with the causes of death in midlife 50,000 years ago. What is total over all causes of the lesser of the % of deaths by that cause 50,000 years ago and the % of deaths by that cause now? My guess is that total overlap is way less than half. So the things that kill us are mostly modern. The things that we evolved to survive are mostly ancient. And we are a species controlled by the brain, mostly by the subconscious brain, which is basically a collection of ancient survival mechanisms and ancient survival inhibitions. Our brains are proud of removing us from our roots and strive to accelerate our separation from what we are prepared to deal with, which introduces just a few changes that appear to our conscious brains easy enough to mitigate in the long run. But our brains are much better at handling the short run and are absolutely confounded by choices involving both the long run and short run. IOW, we live by deep myths and the myths are dying.
