Is Football Kosher?
Some rabbis ruled that boxing, because of it's high risk of serious injury including brain damage, was forbidden. But to my knowledge, no rabbi has ruled that American football is forbidden – even though the evidence that a high percentage of football players have brain damage is now clear. The brain damage causes Alzheimer's -like symptoms and an increased rate of suicide. Shouldn't playing football (or watching it, for that matter) be forbidden? If not, why not?
