I strive to stay in shape, so it's reassuring that experts link regular exercise with good health. But the flip side of this makes me worry for some people, as lack of exercise is now deemed more harmful than obesity.
Researchers at Cambridge monitored the health of over 300,000 Europeans for 12 years. They found that inactivity causes 676,000 deaths each year, almost twice as many as obesity. People who exercised and had slimmer waists suffered less from cardiovascular disease and type 2 diabetes.
