سؤال
A 50 year old Australian male is watching the news in 2014 and hears that the current life expectancy for males has risen to 80 years.Does this mean he can expect to live
For another 30 years?

A)Yes.If life‐expectancy at birth is 80 years and he has already lived for 50 years, he can expect to live for an additional 30 years (50 years + 30 years = 80 years)
B)No.If life‐expectancy at birth is 80 years and he has already lived for 50 years, he can expect to live longer than 80 years, because the probability of dying differs over the
Life‐course.
C)It is not possible to answer this question, because mortality rates in the population will change in the future.
D)None of the above.

Community B.Which of the following is correct?

A)Community A has a younger population than community B
