Wow, scary thread! I've been concussed a couple of times from bicycle crashes and the 2nd time I crashed they did a Cat-Scan and the Dr. said he could see evidence of my previous concussion 20 years previous!

And I thought that was scary. But after reading the posts above, I can only guess I was just lucky not to have these kind of problems. At least not in the past; maybe in the future though . . . you never know.
