"In this world nothing can be said to be certain, except death and taxes."
-Benjamin Franklin
Poets rage against it, daredevils defy it, undertakers depend on it, but the end comes for all of them in turn. Still, as Franklin observed, the problem is death and taxes. While facing your own mortality isn't pleasant, proper estate planning can save you - well, not exactly you, but those you leave behind - a lot of trouble. Avoiding these common mistakes is a good start.
