If you were offered knowledge of exactly when and how you'll die, would you take it? Why or why not?

I wouldn't want to know that. Imagine even if you get to know only a part of that knowledge, for instance, you get to know that you will die on a Tuesday or within a specific month. With that information in mind you would dread every upcoming Tuesday (or a specific month) and in the end it all may lead up to a self fulfilling prophecy.
