My hubby thinks he is doomed

My husband feels since he had an angina attack that he is doomed, because heart disease runs in his family, that it took his dad in his early 50′s.  We have been discussing about getting insurance and he thinks he is going to have to get high risk life insurance.  Well I don’t feel that way, since he quit smoking and passed his heart test.  We have to go to a party for his Uncle who by the way is going to be 80 years old.  So I really think my husband isn’t doomed and wish I could get him to stop thinking about that.
