Why? Because if you decide you need life insurance for a longer period of time after you buy your term life plan, you are guaranteed the option to renew your coverage for an additional period of time when your original term life insurance policy ends.
With guaranteed renewability you won't have to take a medical exam to prove you are healthy and qualify for life insurance at time of renewal. However, your renewal premium will be based on your age at the time you renew coverage for an additional term (of up to 10 years).
