I know this is intended to be humorous - and, it is. However, if it was a serious question - the answer would be:
Nothing a lot of love, affection, and a good diet wouldn't take care of!
You see -- most of these types of things are caused by chemical-imbalances in our bodies - usually initiated by the build-up of the 'junk' ( read "laboratory chemicals" ) in the food we eat, or that we get from other 'environmental' sources. A proper diet will virtually-if-not-literally make them all go away - and, keep them away.
The difference between 'virtually' and 'literally' is a matter of just-how-good of a diet one can obtain and maintain.
