What scares me

I hear this so much, and it truly scares me. The fact that a person can be going along, living a good life, minding their own business, planning a future and a piece of space debris...or more likely a drunk driver, comes out of nowhere and game over! The uncertainty, the unfairness, the randomness...the lack of any control whatsoever in one's own future, frightens me beyond measure. One can not live a life asking, what if? It would paralyze you beyond measure. But it's a scary world.
