The couple of times I've been close to death, I don't remember feeling fear. It's difficult to explain, but in the moment I felt excited. I don't believe in an afterlife, but I think in that moment I honestly expected there to be something more. I even remember thinking 'finally I'll get to see what comes next'.
No, I am grateful. Without death, I would live forever and not a single thing would matter. The fact that life is finite is what makes it precious and beautiful.
Besides, I am just a biological machine. My brain is a computer. It can only experience life, so in that sense I will live forever, I will never experience anything else. If you fear death, think about the years before you were born. They are indifferent to you, right? So is the time after.
The fear of death is just a product of evolution. Without it, our species would have never let us get this far. Understand that, and you will see how irrational that fear is. Overcome it, and death will empower you. You have nothing to fear in life, nothing to lose. Everything will be over soon, no matter what, forever. Do whatever you please, follow your instincts. You will be an happy animal.
