OK, I gotta question:

	I'm told, through various reputable sources, which I can't remember
just this minute, that the majority of the human race lives on a 25 hr 
schedule, and some on as long as a 27 hr schedule. By schedule, I mean
circadian (sp?) rythms and such like. Now this is all very well, and would
explain admirably why I can't get up of a morning, but, being a scientist
'n'all, I can't help but think that there ought to be some good reason
for this. After all, the Earth has been running on a 24 hr day for quite
some time now, and I'd've thought that we'd have caught up by now. Anyone
got any ideas?

	On a related note, being an astronomer, I'm often faced with the
transition from a day schedule to a night schedule and back again. Some
years of practise have led me to the conclusion that I can only grin
and bear it. Anyone got any better, more scientific ideas of how to
deal with jet-lag?

	Tim
