Since many people are fearful of running out of money before they pass on, there is one product that they should definitely look into. These products are called income annuities (or simply annuities). Annuities are essentially the opposite of life insurance: When you buy life insurance, you’re spending money to protect your survivors against the risk that you’ll die too young, whereas buying annuities protects you against the risk of dying too old (outliving your savings).
