total disability
(j) The term total disability means any impairment of mind or body which continuously renders it impossible for the insured to follow any substantially gainful occupation. Without prejudice to any other cause of disability, the permanent loss of the use of both feet, of both hands, or of both eyes, or of one foot and one hand, or of one foot and one eye, or of one hand and one eye, or the total loss of hearing of both ears, or the organic loss of speech shall be deemed to be total disability. Organic loss of speech will mean the loss of the ability to express oneself, both by voice and whisper, through the normal organs of speech if such loss is caused by organic changes in such organs. Where such loss exists, the fact that some speech can be produced through the use of an artificial appliance or other organs of the body will be disregarded.
