My nephew had a pretty severe concussion he got playing high-school football. Fortunately he listened to his dad and hung-up the cletes at age 17. Now a third year college biomedical student and doing great.
Good stuff... That’s what kids and young people in sports should be directed to do.
It’s tough because playing sports isn’t about money when you’re young, it’s about the love of playing and participating. One concussion is enough, if a young person suffers one concussion they should be directed away from physical activities that can result in concussions.
There are sports that do not involve possible trauma to your skull, like tennis or golf. And that’s the direction that people who suffer a concussion should be directed towards.
