Can sitting shorten your life? A new study suggests it will.

I read an article today regarding sitting and how it can shorten your life (http://www.usatoday.com/news/health/2010-07-27-sitting-death_N.htm) .  In a 14 year study, they found that people who sit for longer periods of time (many of us do this at work for hours) are more likely to die from heart disease than those who get up and move around alot. Apparently, mixing alittle exercise with sitting did little to change the outcome.  Apparently, there was a sedentary physiology that develops with those who sit alot.  Please read the article.  Very interesting.
