Well I thought Penquin's rationalisation was excellent and interesting but long posts won't drive me away. But not everyone has the stamina/reading skill to wade through a whole page of detailed scientific information. Like some people can read pages of instructions and others don't/can't. Different strokes for different folks. Anyone is welcome to pass over anything they don't want to read, short or long, but if anyone wants to be pedantic, go for it. It's your choice!
