"Using my understanding of quantum theory, I have developed a method for making me live forever.
I have this gun hooked up to a device which measures the spinning of a single quark. If the quark is spinning clockwise, then the gun will fire, but if it isn't, I remain safe.
Every time this machine reads, two realities will be created: one where i am shot, and one where I am not.
In one reality, I will have never been shot at all!"
