Scenario: A life insurance salesman, who happens to be a trusted friend of a relatively-new-but-so-far-trustworthy friend of yours, is trying to sell you a life insurance policy. He makes the surprising claim that after 20 years of selling life insurance, none of his clients have died. He seems to want you to think that buying a life insurance policy from him will somehow make you less likely to die.

How do you respond?

edit: to make this question more interesting: you also really don't want to offend any of the people involved.
