Most of the world IS suffering from a disorder, but it's not one you can treat with a pill. It's a diabolical disorder, which fathers the religious disorder, which results in disorder of pretty much everything else. Fortunately, the treatment is free, safe and (excepting exercising the morbidly lazy will) painless. You can pick up the cure for this disorder in your local Traditional "RC" Church.
Until we fix that disorder, however, we're probably going to all increasingly be pressured to drug ourselves and the children. I'd say why, but then someone might accuse me of having a disorder.
