P.S. I don’t want to insult you, but you might want to check your head – I forget how this illness is called, but there exists a condition when a victim becomes unreasonably obsessed with cleanliness and is panically afraid of anything non-sterile. I suppose there are many stages in between too, so it isn’t like you either just don’t care or are mad as a hatter.
