In our considerable experience, lefties are under more stress from the push to become right-handed from an early age, but what we observed was stammering and learning disability and if they're going to start saying those are health risks we may as well throw in the towel.

Maybe I've seen too much Star Trek, but I thought there was a difference between "mental illness" and mental disease -- an illness that affected the mind, like this rumor recently that some kids get severe OCD after having had strep. (I'm not too sure about this. If you just finished fighting off a life-threatening infection wouldn't you be worried about germs?)
