Author's Note: 10 Facts About Biological Rhythms

Daylight saving time is a blessing and a curse. Pushing the clocks ahead an hour come spring means that the sun will still be up when I leave my office. This, of course, allows me to continue believing that I am a real, live human being rather than some sort of hunchbacked, cave-dwelling hermit who slinks around under cover of darkness. On the other hand, it seems to take me weeks of adjustment to get out of bed on time after the change. That's because I like to get up when the sun gets up. Call me crazy, call me a damn dirty hippie, call me late to work, but it is my humble belief that alarm clocks are for quitters. If the Good Lord wanted us to get up earlier, he or she would bring the sun up accordingly.
