Corky: Be more aware of concussion dangers while surfing

I recently got an email telling me how the Pepperdine Surf Team was working with a new mobile app called HitCheck to monitor concussions while surfing.
This interested me because, as a long-time surfing coach, I can attest to the number of times people get hit in the head with their boards.
The first thing we tell beginners is that when they fall off they should stay under water for a couple of extra beats and then come up protecting their heads with their hands and arms.
But do they listen?&nbs
