Had a high school buddy who I introduced to motorcycles. I’d been riding since I was about 5 and absolutely love it! Helmets were always a very big thing in my motorcycle home. He was always made to wear one when riding at our house. He bought his first one a year out of high school. Back in the day, (no idea now) OK didn’t require helmets to ride. He decided he was far to cool for a helmet. Second week he had it someone pulled out in front of him and he hit the back of their car. It was a residential neighborhood and police confirmed the accident happened at about 15mph. His only injury was hitting his head on the handlebars and doctors released him with a goose egg. Several of us were there when he was released. Within 24 hours he was in a coma. Then his brain shut down. His parents pulled the plug 6 months later… Helmets people! Helmets!!!
