So, we've learned that sitting is very bad for your back, and that it's not just bad for your back, but that it's literally killing you.

Well, now it's not just getting fat and getting diabetes or heart disease; it's cancer. Like, all of them.

Physical inactivity is linked to as many as 49,000 cases of breast cancer and 43,000 cases of colon cancer a year in the United States, said Christine Friedenreich, an epidemiologist at Alberta Health Services-Cancer Care in Canada. ... But her findings also suggested that an estimated 37,200 cases of lung cancer, 30,600 cases of prostate cancer, 12,000 cases of endometrial cancer and 1,800 cases of ovarian cancer could be prevented if people were more physically active.

The work adds to a growing body of research indicating that prolonged sitting has lethal consequences, regardless of how active people are the rest of the day.

"It seems highly likely that the longer you sit, the higher your risk [of cancer]," said Neville Owen, head of behavioral epidemiology at the Baker IDI Heart and Diabetes Institute in Australia, who also presented findings at the meeting. Owen's study showed that U.S. adults, on average, sit 15.5 hours a day.

...
However, there's good news. It seems that long, uninterrupted periods of sitting are what is most unhealthy, and that by frequently breaking up long bouts of sitting with just a few minutes of light exercise, a person can lower his or her cancer risk. Owen's study found that one- to two-minute breaks from sitting can reduce levels of molecules in the body that are linked with cancer risk.

If you follow the link on "prolonged sitting has lethal consequences", it brings you to an article that suggests the "best" type of chair for not killing you. Unlike the above post with the infographic that says it's best to sit at a 135° angle, this article says it's best to be perched on a stool so some of your weight is still on your legs. They also mention this chair (a Swopper) that sits on a spring that's supposedly good. The only problem is it's $700. I think i'll just stand. That's free.

Joe Jackson wuz right!
