I heard an interesting account about the phenomenon of jetlag yesterday. Some friends, both doctors, know an absolutely blind person who is very talented in his field. While he is in international demand he has, it seems, found that he cannot sucessfully recover from jetlag. Having no light-based information about local day or night his body clock does not reset itself well enough for him to function normally. He does travel internationally but only along lines running more or less north and south.

I continue to believe that destroying night and day by whatever means (obviously I'm thinking about LP) cannot be a good thing for us.

Very interesting - I've never thought about how jetlag might especially affect a blind person before.  That's gotta be very tough.

Thinking about this it might be made worse because I doubt he does things like have the lights on until he goes to bed or throw the curtains open when he gets up. I understand there are some mechanisms (including the skin) for photo-sensitivity that may be involved in timekeeping apart from those relying on vision.
