Whole life insurance offers permanent protection and covers you for your whole life. The premiums are guaranteed to never increase, so you never have to pay more for your insurance then you do when you first get your policy. This is regardless of health problems or changes that may occur. The death benefit of a whole life policy is guaranteed to never decrease for as long as you live. The cash value of the policy that accumulates over time is also guaranteed at a specific interest rate based on the insurance company that you choose.
