Interesting to see that physical inactivity is even way more damaging than obesity, and that even "healthy weight" individuals would greatly benefit from walking or cycling. (Okay, nothing shockingly new but it might motivate some.)

Lack of exercise responsible for twice as many deaths as obesity
A brisk 20 minute walk each day could be enough to reduce an individual’s risk of early death, according to new research published today. The study of over 334,000 European men and women found that twice as many deaths may be attributable to lack of physical activity compared with the number of deaths attributable to obesity, but that just a modest increase in physical activity could have significant health benefits.
