Thanks for the lighthouse story Roger. I've heard that in the early days lighthouses were manned by just two hands until one day one of the keepers on some English station died and the other went crazy having to spend the remainder of his trip with a corpse. Legend has it that after that three men manned the lighthouses so if one died or whatever the remaining two could keep each other sane, or at least as sane as a lighthouse keeper could be. (Many I've known were slightly "odd"but almost all were fairly intelligent)Does anyone know if this story is true??
