Readers of the News Blog will have seen previous articles on exercise and health.  It is more dangerous to have diabetes or to smoke than to be a coach potato, but there are many more coach potatoes than people living with diabetes or smokers, so overall, more people lose their lives from inactivity than from either the diabetes or the tobacco. It also turns out that the marginal gains of more exercise decrease as total exercise increases. Totally sedentary people (about 25% of the US population) have by far the highest risk. This is the basis for an interesting review and editorial in the Annals of Internal Medicine, advocating policy focusing on the totally sedentary,  as well as a news article in the BMJ.
