It answers the question you asked.

Another answer, mine, is that one grandmother flew bombers, jets, spitfires, etc. in WWII and ran a post war international logistics company after that. The other did "stuff" with math.

ie. Both capable of understanding a security posture.

How about your grannies?

You might want to ask well formed questions in future, on a site such as HN the set of all grandmothers is hardly homogeneous.
