Five hours a day on the computer could kill you -

Quacks working for the University College London have worked out that those who spend more than five hours a day in front of the PC are more likely to croak.

Apparently time spent at a computer is as damaging to the heart as time spent lounging in front of a television screen. People who work on computers or watch television for four or more hours a day are 125 percent more likely to suffer a major heart problem than those who spend two hours or less.

Those who work 9 to 5 on a computer should be popping their clogs at an alarming rate.

The study also found a 48 percent increase in deaths of any cause among people who spend excessive time staring at a computer or television screen.

Apparently the results were consistent even among individuals who spent time every day exercising so spending your spare time at the gym had no effect in cancelling out the problem.

Dr. Emmanuel Stamatakis wrote in the study that analysis suggests that two or more hours of screen time each day may place someone at greater risk for a cardiac event. People who spend excessive amounts of time in front of a screen are more likely to die of any cause and suffer heart-related problems.

The problem seems to be caused by the fact that prolonged sitting can cause a 90 percent reduction in a heart-healthy enzyme, lipoprotein lipase, which could explain the results. Inflammation and metabolic problems caused by long periods of inactivity are undoubtedly also to blame.

The report suggests that anyone that sits on their computer for extended periods of time to take breaks for a brief walk every 20 minutes. Of course this is fine for smokers who always have that excuse, Meanwhile the rest of us need to have a defibrillator on hand just in case.
