Need more motivation to hit the gym? If nothing else, this depressing news may help. A U.S. National Research Council panel has found that life expectancy isn’t rising as fast in the United States as it is in other wealthy nations, thanks to cigarettes, overeating and lack of exercise. Yes, the reason kids born in Japan today can expect to live five years longer than those born in America results from smoking (a 40 percent lag in life expectancy for men, 80 percent for women) and obesity (20 percent for men, 30 percent for women). The gap between Europe and the United States isn’t as great, but it’s growing. Pardon our French, but c’mon, America, shape the f*** up!
