Clocks "fall back" early Sunday, meaning the semiannual reprise of circadian battle lines as much of the world reverts to standard time.
Yes, we get to make up that hour of sleep so rudely taken away by that dreaded of all traditions: daylight saving time.
But many wonder why we have to go through this rigmarole each spring and fall, beyond the important reminder of changing the batteries in our smoke detectors.
Daylight saving time began in Europe during World War I to conserve energy, then briefly migrated to the United States in 1918. It became a fixture in America after World War II.
The theory goes that by reducing the amount of indoor light used before bedtime, less electricity is used. A recent federal study found this to be the case. However, researchers have said the savings are negligible in modern, 24/7, computer-driven world.
In any case, synchronize with your community. Move clocks back an hour at 2 a.m. Sunday.
The sun will rise and set earlier. Children won't have to wait for the school bus in the dark. That air conditioner may not run as much.
But there will also be less sunlight for outdoor activities and shopping. More cars will be out at night, when visibility isn't as good. Many people will vote after work Tuesday when it's dusk or darker.
Ah, the pros and cons come out like clockwork each November and March.

Just remember, you may change your mind come March 10, when you give back that hour of shuteye.
