Americans do not live as long as many other nations. What might be the reasons?
Live long and prosper was Mr Spock's salute, but the interesting thing about Americans is that, prosperous as they may be, they do not live as long as many other nations. British females had a lower life expectancy than Americans in 1980; now they can expect to live 1.6 years longer. British males have gone from being roughly level to being more than two years ahead http://econ.st/13vcame
