Millions of people sitting yapping on discussion forums will die.....

Inactivity increases with age, is higher in women than in men, and
more prevalent in high-income countries, the researchers found.

A second study, comparing physical activity levels with population
statistics on diseases like diabetes, heart problems and cancer, said
lack of exercise claimed more than 5.3 million of the 57 million deaths
worldwide in 2008.

It said inactivity was a risk factor comparable to smoking or obesity.

Lack of exercise causes an estimated six percent of coronary heart
disease cases, seven percent of type 2 diabetes (the most common form)
and 10 percent of breast and colon cancers, it said.

Reducing inactivity by 10 percent could eliminate more than half a
million deaths every year, the report said, adding that the estimates
were conservative.

The human body needs exercise to help the bones, muscles, heart and
other organs function optimally, but populations are walking, running
and cycling less and less as they spend more time in cars and in front
of computers, the investigators said.
