I get what you're saying. And seeing your detractors here, I can't argue with the data.

I wonder though if we didn't trade the low-hanging fruit of lung cancer for the kinds of things that kill us now. I won't argue that we didn't add a decade to our average lifespan, but it does seem our lives have become more sedentary than they were. (Mine certainly has—but then I'm also forty-plus years older, ha ha.)

I wonder how 70's man and 70's woman fared who didn't smoke or live with a smoker—if you compared just that group with modern man and woman.
