Your brain on civilization.
One way to think about our own brain, personality, and physiology is to consider our sensitivity levels to various neurotransmitters and hormones. Being desensitized or oversensitized to various aspects of our own chemical control systems will drive our behavior and emotions. This happens whether we’re aware of it or not, so we might as well try to understand what’s going on in our brains and endocrine systems.
Most people who live with artificial light, electronic devices, internet connections, abundant food, processed foods, and other conveniences of modern life will eventually experience some degree of being “out-of-whack” in terms of neurotransmitter and hormone sensitivity.
