As for stirrups.. now dont laugh but when I was asleep under the anaesthetic.. I had the most awesome dream about riding along the beach.. it was great until I slipped out of the stirrups on one side and had to correct myself.
I was asked when I woke up if I was comfortable and if I'd had a nice sleep... then I was asked "what were you dreaming about as you kept shifting about and then your foot slipped out of the stirrups which hold up yours legs during the op"... HOW WEIRD!
