Kim -

A person's life expectancy is the length of time the person is expected to live, given his or her current age. A person with a life expectancy of 10 years has a 50% chance of living less than 10 years and a 50% chance of living more than 10 years.

A person's life expectancy is based on the mortality experience of a large sample of people as summarized in a mortality table.
