Former fighter and Ivy League football player Mark Tullius wanted to support his friends with traumatic brain injuries (TBI) and chronic traumatic encephalopathy (CTE). But when presented with a scan of his own grey matter, his life changed forever. After years of lying to himself and insisting he felt fine, Mark had to face the fact that his time on the field and in the cage had caused potentially irreparable damage inside his skull. Tired of throwing in the towel when things get difficult, Mark committed to make his recovery an adventure in health, happiness, and self-discovery. And now he's sharing his journey, research, and joy with you, hoping that you, too, can recover and walk out of the darkness. A powerful balance of scientific fact and personal triumph, this testament to the strength of the human spirit is impossible to put down. If you want a change of pace from heavy medical tomes about TBI and CTE, Mark's true and incredible saga is a life-changing "must read!" - D.
