That's a really interesting article, although I can't see how it applies to us since none of us have symptoms mimicking ALS. Although it would make sense that repeatedly getting concussions and being battered in the head is a bad long term idea. And here I thought football players had enough problems as it is (weight, heart, blood pressure, steroids, shorter life span, etc). I didn't realize they were also getting ALS at higher rates than the general populace. It's a good idea not to be a professional football player.I'm very familiar with Gehrig since I am an amateur baseball historian and have been running historical baseball simulations since I was 12 years old. He was legendary for (like the article said) not only playing through pain, but for having concussions and lots of head injuries. He was also a stubborn son of a b who would very rarely ever see a doctor or tell people if he wasn't feeling well. It wouldn't surprise me at all if he didn't actually have "Lou Gehrig's Disease." For one thing he was far too young. I would buy it completely if he atrophied and died from having some sort of long term massive brain trauma instead. That would fit his storyline a lot better than ALS would.
