Daylight Saving Time

From Wikipedia:

The practice is controversial.[1] Adding daylight to afternoons benefits retailing, sports, and other activities that exploit sunlight after working hours,[2] but causes problems for farming, entertainment and other occupations tied to the sun.[3][4] Traffic fatalities are reduced when there is extra afternoon daylight;[5] its effect on health and crime is less clear. . . .

The effect on health is more clear now.

On Benjamin Franklin's role:

During his time as an American envoy to France, Benjamin Franklin, author of the proverb, "Early to bed, and early to rise, makes a man healthy, wealthy and wise", anonymously published a letter suggesting that Parisians economize on candles by rising earlier to use morning sunlight.[13] This 1784 satire proposed taxing shutters, rationing candles, and waking the public by ringing church bells and firing cannons at sunrise.[14] Franklin did not propose DST; like ancient Rome, 18th-century Europe did not keep accurate schedules. However, this soon changed as rail and communication networks came to require a standardization of time unknown in Franklin's day.[15] . . .

Clock shifts disrupt sleep and reduce its efficiency.[57] Effects on seasonal adaptation of the circadian rhythm can be severe and last for weeks.[58] A 2008 study found that although male suicide rates rise in the weeks after the spring transition, the relationship weakened greatly after adjusting for season.[59] A 2008 Swedish study found that heart attacks were significantly more common the first three weekdays after the spring transition, and significantly less common the first weekday after the autumn transition.[60] The government of Kazakhstan cited health complications due to clock shifts as a reason for abolishing DST in 2005.[61] . . .

I think we should abolish it here. Sounds like a simple way to eliminate heart attacks by 5%, which is hardly insignificant. (And the 5% decrease in heart attacks when DST ends does not in any way compensate for it, especially if you've already had a heart attack and are possibly dead.)

I know I, for one, will be dragging my ass all next week.
