Life insurance refers to an individual insuring their own life or health. There are several types of life insurance policies including whole-life, term life, and annuities. Life insurance policies have certain features such as surrender values, non-forfeiture clauses, and restrictions. Annuities can be either immediate, with the first payment due immediately, or deferred, with payments starting at a later date. Permanent health insurance and group policies are also types of life insurance available.
