I've noticed so many top sportsmen having ongoing problems following concussion recently. And not just in the obvious sports either. It's probably just because I'm hyper-vigilant for it at the moment, but it's amazing how often I am seeing it.

And it's almost always played down, minimized, referred to as 'mild' etc, presumably for financial reasons.

These sports players, and the millions of people who see them as their role models and think it must be ok to get concussed and keep on playing, are all being put at risk. I was in that category, and I had no idea that this could happen. Sure I was naive, but why did noone tell me?
