Now let’s expand the expression. “A man’s gotta do what a man’s gotta do. That is why George went bungy jumping at age 65”. Here we move from a generic to a specific even though the generic and specific are tied together (George is a real life example of the generic man doin what he has to do). This is a common pattern in speech. What I am suggesting is not some crazy, out of left field, grammatical gymnastics.
