Time Change Health Effects?
Don't forget, we move clocks back an hour this Sunday - an extra hour of sleep that may be good for you. This is fascinating, if true.

Heart attacks decrease by 5 percent the first Monday after the time change, and by 1.5 percent over that week, according to an analysis in this week's New England Journal of Medicine. The findings are based on 20 years of data from a Swedish registry of nine million residents.

The springtime transition to daylight saving time poses more of a health hazard: Heart attacks increase by 5 percent over the first week after clocks are pushed back an hour, spiking by 10 percent on that Tuesday, epidemiologists at the Karolinska Institute in Stockholm found.

I have my doubts, no offense to Swedish scientists (or Swedish hearts). For one thing, if screwing with your sleep schedule that slightly was that bad for you, wouldn't we notice a similar heart attack increase among people going through jet lag after long flights? I dunno, maybe that does happen? I've certainly never heard of it though.
