Mammography is estimated to save about 1 life in every 1000 women. “Participating in annual mammography screening … has roughly the same effect on life expectancy as reducing the distance one drives each year by 300 miles” (Gigerenzer 2002, pp. 60, 73). Which of the following do you think has the closest effect on life expectancy as that of smoking throughout your entire life?
a. Taking a commercial airline flight once a year
b. Driving about ten times as far every year as the average motorist
c. Drinking a cup of coffee every day
d. Eating a fast-food hamburger once a month
e. Never having a mammogram (if you are a woman)
