The Risks of Sleep Debt

"For years, sleep researchers have been preaching the dangers of lost sleep: People who are fatigued can't pay attention to routine tasks, have trouble learning and are prone to a laundry list of health problems, from depression to high blood pressure," says Kathleen Facklemann in USA Today

"New research suggests an added risk to losing sleep day after day: Humans and animals that have chronic sleep deprivation might reach a point at which the very ability to catch up on lost sleep is damaged, according to Fred Turek, a sleep researcher at Northwestern University in Evanston, Illinois."

"His research on sleep patterns in rats appeared this summer in the Proceedings of the National Academy of Sciences. That, together with findings from a human study, suggests people who lose sleep night after night might not recover the alertness they need to perform well during the day. So far the studies don't tell researchers whether the damage is permanent. But they do suggest that people who go to work fatigued day after day might perform consistently at a subpar level.

Cell Phones ARE Dangerous

I've said it for years: talking on a cell phone demands your sharp attention and hence it is dangerous to employ a cell phone around vehicles. Now "indisputable" evidence confirms my observation. Steve Rubenstein in The San Francisco Chronicle reports that "A pedestrian apparently absorbed in a cell phone call was struck and killed by an Amtrak train in San Leandro today after he walked around a lowered crossing gate and onto the tracks."

"The victim, a man who was not immediately identified, was struck at 12:30 p.m. by a northbound Capitol Corridor train at the Alvarado Street crossing, about 8 miles south of the Oakland station... None of the 20 passengers or crew aboard the train was injured. That train and two others were delayed and another Capitol Corridor train was cancelled."

"Crew members aboard the Sacramento-bound train told authorities they saw the victim talking on the cell phone before he was struck, Graham said. The warning lights and gates at the crossing were functioning properly."

Draining Your Brain

David Brook, writing in the New York Times, offers a brilliant article called "The Outsourced Brain," wherein he describes how today's technology is aiding some people in abdicating from everyday decisions, and worse, even from basic thinking.

"The gurus seek bliss amidst mountaintop solitude and serenity in the meditative trance," he writes, "but I, grasshopper, have achieved the oneness with the universe that is known as pure externalization.

"I have melded my mind with the heavens, communed with the universal consciousness, and experienced the inner calm that externalization brings, and it all started because I bought a car with a G.P.S."

"Like many men, I quickly established a romantic attachment to my G.P.S. I found comfort in her tranquil and slightly Anglophilic voice. I felt warm and safe following her thin blue line. More than once I experienced her mercy, for each of my transgressions would be greeted by nothing worse than a gentle, Make a U-turn if possible.”

"After a few weeks, it occurred to me that I could no longer get anywhere without her. Any trip slightly out of the ordinary had me typing the address into her system and then blissfully following her satellite-fed commands. I found that I was quickly shedding all vestiges of geographic knowledge."
