Problem
In this film clip from the 2009 movie "Brothers," Marine veteran Sam, who was shot down over Afghanistan, gathers with his family. After watching the YouTube video film clip "'A Balloon Triggers Sam's PTSD' Scene | Brothers".
Describe how Dr. Perry, the neuroscientist in What Happened to You? Explains how past trauma can affect us in the present. Then imagine an example of what trauma in Sam's service as a Marine might have triggered his response to his daughter Isabelle who is playing with a balloon. (Give a different possibility than the one that happened in the movie.)
