Sample Key Takeaways:

1) Every person is born in their own unique set of social, economic, and cultural circumstances. We come into the world feeling whole, but life eventually begins to take its toll. Traumatic events, abuse, or neglect can cause children to ache and follow a pattern of frustration, self-sabotage, violence, and addiction.

2) The brain is like a four-layer cake. The cortex at the top is responsible for speech, thinking, and planning. The bottom contains the brainstem, which controls less complex functions such as body temperature regulation, breathing, and heart rate. The complexity of the brain's structural areas increases from lower to higher.
