it's probably an epigenetic disease just like homosexuality.....it will probably become more and more widespread as more and more people continue to eat junk/fried/fatty/milk-laden/high-carb/sweet foods in place of fruits and vegetables. There is no "gay gene" or "pedophilia gene."Homosexuality and pedophilia are surely both mental diseases stemming from prior generations, but they are actually derived from the effects of bad/unhealthy diets on developing embryos. Also involved, most surely, is prior abuse -- abused children are more likely to abuse their children or others'. Screwed-up children generally lead to screwed up adults unless there is some powerful supernatural intervention.
