I have no idea. Neither do doctors. Chances are, a lot of my readers suffer from this disease. You're not alone. Mothers kill their babies.
People kill others for a quarter.
Hell, we've even got pre-teens getting into the murder fad. They can probably eat pizza and not worry. They won't have to worry about losing 30 pounds in a year no matter how much they eat. They won't have to worry about piling 30 layers on when the temperature dips below 60 because their blood's nutrient level is so low that a breeze causes a fever. Nope, they're healthy criminals and scabs of our society.
