To clarify, the 36.5 years life expectancy is not the <i>average</i> it is the <i>median</i> life expectancy. The average adds all number values (in this case, age) then divides by the total # of people. Median is the value where 50% of the people are above and 50% of the people are below so it is not as impacted by 'outlier' values.
