Two more in a plastic bag please

A relative whom I care about forwarded me (and forty-four other people) a chain letter cautioning us about the risk of getting cancer from plastic food wrapping.
That’s nonsense, of course, like everything you receive by email.
The twist? This person — who now is presumably wary of that consarned plastic — smokes as if her life depended on it, and has done so for decades.
The mind boggles.
