Don’t let your kids or teens train or compete in MMA if there is head contact. All concussive trauma is brain damage, brain damage is forever, and kids and teens can’t meaningfully consent to an activity that can have severe lifelong implications. There are safer and better training options for kids and teens that don’t have as high a risk of brain damage and CTE.

Now on the other hand, if you’re an adult and are aware of the consequences then fight, spar, and knock yourself out! I totally support your right to take risks and bear the consequences thereof so long as you’re beating the crap out of other people who have also consented to take the same risks!
