It happened in a car accident
When he was fifteen years old, Hill took to acting out, which culminated in he and a friend joyriding around LA in an SUV.
As the teenager stuck his arm out of the window, the car crashed. It dragged Hill’s arm along the road and leaving it horrifically damaged.
They were going to amputate his arm
Hill woke up to doctors discussing whether or not to amputate. Thankfully for him, they decided they could save the arm. He today calls the scar “One of the biggest things ever in my life”, and a constant visual reminder to work hard and be successful.
