Every insurance contract shall provide that if it is found that the age or sex of the insured, or of any other individual considered in determining the premium or benefit, has been misstated, the amount payable or benefit accruing under the policy shall be such as the premium would have purchased according to the correct age or sex. Such calculations shall be in accordance with the insurer's rate at date of issue, and at the option of the insurer this may be so specified in the policy.
