A disability waiver of premium rider is available, at an additional cost, if you are between the ages of 18 through 59 and states that if you become totally disabled either from illness or injury, you don't have to pay premiums for the duration of the disability (once you show disability for longer than 6 months, you will receive a full refund from date of disability). If you feel you would be in danger of not being able to afford the premium if you become disabled, you should consider this option.
