A Psychological Hygiene Hypothesis?

We Are Not Saved

The hygiene hypothesis holds that by missing out on the normal infections of youth leaves the immune system with nothing to do, and as a consequence later in life it over-reacts to normally benign things like peanuts. What if the same thing is happening psychologically? What if an absence of certain forms of trauma and stress when young lead people to overreact to things later in life which aren't particularly traumatic. In discussing this I bring in the writing of Brene Brown who points out that we're the most addicted, medicated, in debt, overweight adult cohort in history. Given how objectively untraumatic modern life is, why would that be?
