re: childhood development - Arguably the more interesting work on this is how particularly intense acute periods of stress that would register as "trauma" predispositions an individual to things like much higher rates of ischemic heart failure, diabetes, and other health conditions that we might not typically relate to trauma.

Then there's all the standard stuff you might expect, emotional dysregulation into adulthood, drug and alcohol abuse, suicidal behaviour, etc.

See Dr. Vincent Felitti's Adverse Childhood Experience studies for more info.

Don't forget his book "Why Zebras don't get ulcers" [0]
