My friend was struck by ALS. To fight back, he built a movement

Meet Brian Wallach, the man on a mission to give ALS patients help and hope. At 37, Wallach was diagnosed with the fatal disease, known for attacking the nerves that control muscular movement, and given six months to live. What did he do next? He tapped a lifetime of connections, and created I am ALS, a life-changing foundation dedicated to finding a cure or treatment — all while grappling with his own mortality. Longtime friend, Brian Barrett, tells Wallach's unique story in WIRED magazine.
