That's how you'll (and I) die anyway. Car accident, heart failure, organ failure, suffocation etc. will all be a surprise when it happens. I think it's important to not fear the inevitable and hold on to the idea that you don't know how you got here to begin with so it's just another new adventure. Humans have a genetically gifted curse in our ability to fear and make concepts bigger than life. Wear your seatbelt.
