excerpt from HBO Real Sports interview with the two doctors about to publish their findings
they said the neurological science journal would publish the study 'tomorrow', not sure if that's happened or not, i don't know if the studio portion of real sports is live or pre-recorded.
either way, they've been studying the brains and spinal cords of athletes who have died from lou gehrig's disease and have found a link to head injuries and the disease, which had previously no known origin. they also researched lou gehrig himself, and found newspaper articles documenting at least 6 head injuries in a two years span (after which he never missed a game, of course, hence the record he held for so long).
i guess the next stop is a big controversy with the NFL and NCAA over how to handle football head injuries.
