Is that a surprise?
Well yes? For example one can have a heart attack and recover very successfully. I get that a life insurance policy might then want to exclude "heart" from the policy, but a blanket "we will not insure you for anything" seems harsh. My better half was 25 when she had a heart attack as the result of a thrombosis and previously undiagnosed atrial septal defect. ASD was repaired and she is fit and healthy but apparently uninsurable.
