Aikman claims that 'through his career, he suffered seven or eight concussions, but there have been no long term effects.'
"No long term effect"? What do you consider "long term?" You're 43 years old, Troy. Who is to say that at 51 your brain will be working the way it would have been without the "7 or 8 concussions?"
Chris Nowinski, a former World Wrestling Entertainment wrestler who was diagnosed with post-concussion syndrome, said "We're finding 10 or 20 years after players stop playing football the thousands of hits to the head they've taken have started a degenerative process that's killing brain cells."
Research well done, Ache-man.
