There are two primary types of life insurance: term and whole-life. Term covers you for only a set amount of time. For example, a 25-year old male that purchases a 30-year term policy will see that his policies coverage will expire at age 55 if it is not converted over to a whole-life policy. Whole-life or permanent insurance on the other hand never expires. You should always consult a licensed insurance agent to determine which is right for you.
