Just before death you are granted one truthful, understandable answer to one question. What would you want to know?
Obviously a hypothetical scenario. There is no way to pass on the knowledge to anyone else. Time freezes for you only, and once you have your answer you are out of this world.
The question can allow you to see into the past, present and future and gain comprehension of any topic/issue. But it's only one question.
Edit: the point isn't "how to cheat death". You can't. Your body is frozen and there is nothing you can do with this knowledge other than knowing it, and die. So if you would rather be frozen in a limbo just thinking of numbers for eternity, be my guest.
Such a variety of replies, it's been really interesting to read them!
What would you want to know? Personally I'd want to see a timelapse or milestone glimpses of humanity's future until the end of Earth's existence (if we survive that long)
When I was younger, we lived on a little farm outside town. Some people from town couldn't take care of their golden any longer, so the dog came to live with us.
About a year later, they asked if they could bring their kid by to visit, because he found out that "went to live on a farm" was usually a lie.
As the chemicals worked their insensate magic on her diaphragm, and her mind winked out leaving her head blank, she fell into a waiting blanket held by God. And the blanket surrounded her, and showed itself to her as a farm, pristine in its morning dew and limitless splendid smells.
