Friedrich Goltz's boiling frog experiment with the slow temperature increase to boiling only worked after he removed the brains of the frogs - all others actually jumped out above 25C+ - when you watch various UK TV shows one can certainly assume that at least some of the actors / watchers must have had their brains removed to be able to endure this. I'm not sure if that applies to the majority of the population (yet) ;-)
