As you know, Daylight Saving Time ends tonight, or technically Sunday morning at 2am.  Sure, you may think it's a pain, but in "Seize The Daylight" Dr. David Prerau concludes that the benefits far outweigh the disadvantages.

The goal of daylight saving time—to use daylight to its maximum advantage—is generally recognized to be of universal benefit. But few people understand how surprisingly controversial this deceptively simple idea has been. SEIZE THE DAYLIGHT chronicles the long-standing debates: Proponents have proclaimed DST's benefits, including saving energy, reducing automobile accidents, providing more daylight for outdoor activities, cutting crime, and many others. But DST also has had many detractors—from farmers to parents of schoolchildren—who have waged contentious battles against it.

Here's one more fun fact:  It's technically "Daylight Saving Time", not "Daylight Savings Time".  If you didn't know that, don't feel bad, more people Google the wrong title than the correct one!

Enjoy your extra hour of sleep!
