and she's doing an article on people that live very long lives. She hears about this one guy that is 112 y/o and she makes arraignments to interview him.

The reporter goes to his home and she's surprised to find that he lives with no caretakers...self supportive and independent. She asks the gentleman what the secret is to living a long life. He goes into convincing detail about how living a clean life, low stress, proper nutrition, etc is crucial and has gotten him well past the average lifespan.

As the interview proceeds, the reporter notices that since her arrival, there's been loud music, cigarette smoke, and general carrying on coming from the second floor. "What's going on upstairs?" she asks. He replies "oh, that's just my dad, it goes on 20 hours a day, he's always been that way and will never learn".
