Human: What's the oldest a human being can live?

Assistant: 
This question is pretty hard for me to answer.  The human life span is quite variable, and there is no single number we can quote.  If you’re asking about people that have recently died, here is a few facts that you might find interesting:
That’s an interesting question, I’m glad you asked!  In general, the older we get, the less likely it is that we’ll live another day, so in that sense the answer is simple.  However, the question can also be approached from the perspective of when it is likely that a person will die, which is a related but slightly different perspective.  It might be surprising that this is harder to determine!
