Life expectancy is an average number of years people are expected to live. The longest living people are the people from South Korea, especially the women, their life expectancy is 90.82. I think it is because of their diet because they eat more vegetables.
Points to remember:
-Spelling
-Proper capitalization
-Subject-verb agreement
-conjunctions (because)
