“I do not fear death. I had been dead for billions and billions of years before I was born, and had not suffered the slightest inconvenience from it.” - Mark Twain I recommend you pick up a copy of Max Tegmark's Our Mathematical Universe. He makes a fairly compelling argument that the universe is a gigantic equation and everything we experience in it, including the experience itself, is one complex wave function. By that argument, "you" are an infinite combination of dependent variables playing out in an intricate enough manner that you have self-awareness. You cannot, therefore, "die" so much as be undefined at points before and after your existence. Of course, everything you are made of is also just an expression of the same equation and as such, it's all a big interconnected system. The uncomfortable aspects of this theory include free will as illusion, consciousness as falsehood, etc but hey. Makes more sense than the transhumanists.
