No, it's not far off from that. It's probably not unlike the guy who's having a lung removed, lying in the bed, and getting a sick benefit while having the lung removed. You would validate the medical certificate. You wouldn't investigate whether or not it was the responsibility of the guy getting a lung removed since a doctor told him ten years ago that he should quit smoking. You wouldn't investigate that.
