Thanks! I just sent a message to that doctor in the video who said concussions at "10,11 or 12" make you particularly predisposed to future concussions in the long term. I had one at 9 which definitely had that effect but noone ever believes me.Would love to get my hands on the evidence he based that statement on, when I bring it up most people, including health professionals, stare at me like I've just said my concussions are caused by aliens

Those two kids running into each other made my head physically hurt did they have to show it twice?
