life expectancy

Today in class, we went over our test from a week ago and I got a 100 so that was good! I found a lot of the questions to be easy because I had remembered going over most of them in class. Today was the first day Mr. Schick had exploded so that was something....new. After that chaos, we began talking about life expectancy which is the average number of years to be lived by a group of people born in the same year. The highest life expectancy is in Monaco, located near the Mediterranean Sea. They have a life expectancy of 89 years old while the US has a life expectancy of around 79 years. I think it is shocking to think that in Chad, people living there are only expected to live til their 50's.
