several new studies show prolonged sitting is now being linked to increased risk of heart disease, obesity, diabetes, cancer, and even early death.
This is an article that discusses some negative health ramifications of being sedentary. It makes good sense, to me. Television, desk jobs, video games (and in my case, quilting) aren't physically healthy, especially if that is all you do. Sounds obvious but I suspect it is more than just not consuming calories.
