My co-workers daughter plays volleyball and was out of school for 3 weeks due to a ball being hit into her head.

I played multiple contact sports in Texas schools, decades ago and with research coming out, wonder if my mental potential or others was damaged by the some of the hits I took or delivered. The MMA training I did as an adult was much safer injury-wise.

You can be part of a team without being in a contact support. You can also workout with out increasing the chances of getting shredded by an outsider linebacker or a cut block or 90 mph fastball.
