Daylight Savints Time

Energy Saving: At best, not enough to be noticeable or statistically significant, and in many cases actually increases energy consumption due to the need for more heating in the mornings and more cooling in the afternoons.

Increases "Leisure Time" and Boosts Economy: Won't help in a recession. Extra daylight may benefit shopping but may hurt other industries like bars or theaters or in front of their television screens where most people go when its dark. With consumer confidence crazily low, DST this year probably won't help a bit. This isn't the middle ages, we don't need sunlight to have fun. + Show Spoiler + Also, some argue that the time shifts lead to productivity losses and may actually hurt the economy.+ Show Spoiler +

Health concerns: Extra sunlight is never bad, unless its so much that you get cancer (Tropics region) or for half the day there is no sunlight, affecting mood etc during working hours, reducing productivity (Hello, Alaska). Extra sunlight may encourage excercise, but personally, I like to exercise when its dark. And, as always there's the jet lag effect of shifting time zones.....

So in conclusion, DST offers marginal benefits at best, yet many are led to believe in the contrary. I don't see the point of messing everyone's schedules up just to have potential returns. Risk assessment says that's not worth it.

I thank wikipedia for all the information!
