Maybe you're an outlier dude, and I'll have to dig up some studies but 5 diagnosed concussions is on the high end as far as I've ever known, but especially now in football etc.I'm using myself as an example because I played sports and was very active. I've never played football, hockey or any impact sports until college. By the time I was in college I had more than 5 concussions. 5 to 7 concussion is low for those who play high compact sports. I can't use anyone else as an example of "It's high compared to most humans living today." because I can only speak of my own experience..
I'm pretty sure many people in here have had more than 5 concussions.
Did you know you can't even enter certain full contact fighting comps if you have a history over just a handful of diagnosed concussions? They won't even let you fight, and you have to provide medical files to prove it (and that you don't have HIV etc).
Let's keep medical concussion separated from hitting your head, getting tackled, etc. Big difference.
