Additionally, it may be given as a precaution after a first concussion (car wreck, for example), even if that person is unlikely to be "banged on the head everyday"
I’m sorry, what? There are two ways I can interpret what you wrote. “Should pay” as in the people who play sports should buy their own concussion medicine. Which is okay I guess? But nobody talked about financing.
Which makes me think you mean “should pay” as in people who choose to partake in sports should suffer harm (as in pay the metaphorical “price”). Is that how you mean it? Because that sounds extremely cruel and twisted morality. There is nothing “should” about that. That makes it sound as if these people deserve the harm even if we could prevent it.
But no I definitely didn't mean the tail end. Sorry if you read that into it; I would never say that.
In that case I agree with you.
