Freud turned out to be wrong about a lot of things, but a new study is validating his most basic belief: that childhood trauma can dictate the course of the rest of a person's life. Children whose families have experienced poverty, divorce, mental illness, substance abuse, jail time or death were twice as likely to have problems in school as children whose didn't. They were also more likely to suffer from serious health problems. While we can't control fate, there is something we can do to improve kids' chances of surviving life's tragedies intact: teach them to practice resilience.
