I was washing dishes for my mother and she kept putting her food processor blades directly in the sink too - almost got sliced once! At least it was "almost."

Some of the posher (and older) houses in England do that - have the WC separate from the other rooms, but these days, most do not. My husband was reading the other day about how closing the lid before flushing can help avoid the particles in the air - but he has yet to follow through, lol. I'd give a lot for a bidet, but those basically don't exist in the US, and even in the UK, it is in the realm of the older/posher house.
