My husband use to be a certifed insurance agent in Alabama. Not sure I remember all the technicalites, I could ask him, but diving, race car driving, and motorcycle racing and jumping from a plane was not insurable, prior to the fact. Thank God I got my policy before I started cave diving and I damn sure I keep the premiums up to date. Once you are already under a policy, they can't really do anything and yes I was under a policy for the American Institute of CPA's. Of course I don't get the preferred rate for my age, ..but I am insured ..
