smokers die younger?

Arnott once again raises the myth that smokers die prematurely; this is easily refuted.Allow me to give you an example of why these studies show misleading results Suppose that you were to compare the mortality of people who did their main grocery shop at a discount store, to the mortality of people who shopped at an expensive/high-end grocery store, You would most likely find that the people who shopped at the discount store died younger than those who shopped at the up-market store. You might (erroneously) conclude that it was the products being consumed that affected mortality, when in reality the two groups are not directly comparable, as people who shop at up-market stores tend to be wealthier and live longer anyway . This scenario explains why for example, cigar smokers appear to live longer than non-smokers. The reason being that cigar smokers are over represented in the most affluent echelons of society. Professor Peter Finch , when analysing Australian smoking mortality, found a difference in life expectancy of only a few days. this might be explained by the fact that Australia is a society that has a less noticeable differential between rich and poor.
