This is one of the best descriptions I've read. It reflects my experience. As you think on the impact of each cumulative concussion in a person's life, consider this:
"I think we all need to remember that TBI is not only a journey; it is a metamorphosis. It’s not a broken leg or arm; it’s a new way of life. The hardened shell of injury that closes around our loved ones, cutting us off from the people we knew, is with time shed away, and a new creature is revealed to us. This can be painful, because we miss the caterpillars they were. And they often miss themselves too. And yet, everyone knows that when they see a beautiful butterfly, the caterpillar is still there flying too."
