HW due: Read this article and answer the
question below.
The facts in the article are correct. The average age at death of rock stars
is indeed lower, on average, than the life expectancy for the general
population. However, what simple explanation is there (other than the one
proposed by the author of the website, that is)? Think critically, and try to
use what you have learned in our class.
Hint: Mr. Hansen has lost several
friends over the years. One died at age 14, one at 16, two at 18, several in
their 30s, one at 69, one at 72. Their average age at death was even younger than that given for the rock
stars! What is going on here? Is it immoral (or, at least, unsafe) to be
friends with Mr. Hansen????? Figure this one out. Does it make sense to
compute the mean age at death of Mr. Hansen’s friends, or of rock stars, for
that matter? Why or why not?
