The ultimate question

If you knew you could ask a question, whatever question even from those human beings don't know the answer, and the answer to that questions was the last thing you could learn before dying, what would that question be?

When I was a kid, I was fascinated by Bermuda triangle and all the strange mysterious stories around it. Even once I had promised myself to go there and see what's behind it when I got very old! This is perhaps one of the questions I'd to hear the answer, even now. However, I don't think that would be my ultimate questions. In fact, I haven't thought about it really. On top of my mind, when given the opportunity to ask such a questions, I would probably look at the world ( I am imagining I've got so big to look at the universe at a glance) and ask "so what?" I think for many, this is the question.
