Eechsa!!

Struck me. All the things we generally associate with repulsive and disgusting (or the more colloquial "eechsa") like excrement, vomit, bodily fluids, etc etc ..... it's the moisture or water element which engenders the human aversion.

Take away the moisture of any of them and we amazingly no longer relate to them the same psychologically even though you're left with basically the same exact elements as before.
