@Thomasdcornwell ,
I've a degree in bacteriology, well obsolete but not always wrong, and am mixed re toilets after all these years. I don't understand toilet fear much, except that I may now not be able to rise - I'm sort of kidding, as I suppose I can escape otherwise.
The times I suffered horribile-oma were not from toilets, but certain cafes or oyster bars, a bit later on.
