Clearly you are not diagnosed by the response you just gave. CTE is rampant in your gord. Sad that parents would expose their kids to this and disguise it as being “tough”. I’ve got news for you....millions of years of evolution have proven that the human brain is extremely sensitive. We are thinkers not brawlers.
Then quit being a hypocrite and watching football and posting on a football board. My wife works in a medical clinic that rotates clinics, one day could be ENT, the next could be dermatology, etc and one of the clinics is concussion. Based off talking to the doctor, I am comfortable with him playing if he chooses to. Like I said you can't live in a bubble. Even people who do can still have an accident.
If you choose not to let your kid play football that is your choice, but quit being such a pompous ass and belittling others. Add for your comment that the human race are thinkers and not brawler we are actually both. The human body is not as fragile as you make it sound. It hand handle abuse, obviously there is a limit but it doesn't break at first sign of it.
