Re: [math-fun] effects of various (e.g. dietary) behaviors on your all-cause mortality (oversimplified picture)

How should we interpret this graph? I'm willing to believe that smoking is bad for your health, but beyond that, it's something of a puzzle. If the death rate from smoking is 2.7x nonsmoking, does it follow that, since American life expectancy is 80 years, that smokers only live to be 30?
