That’s wild. Never had a crash I couldn’t remember.

Yeah, me neither. I have very specific, almost slow motion, memories of each crash. But I have never had a concussion.Friends whose heads have hit hard to where they broke helmets and clearly had concussions don't recall anything from crashes. I have had friends crash and the first indication that we need to call 911 was that they didn't know what had happened and then 2 minutes after learning what had happened were again asking what had happened.
