Yeah. Being dead is no biggie. Why should it be? We simply cease to exist , just as we did not exist for the aeons before were born.
BUT, dying tends to be an experience for most people. THAT terrifies me, as it does all all human beings and many other animals as far as I can tell… This fear is instinctive. In fact survival is our most powerful instinct. were it not it’s likely our species would have ceased to exist a long time ago, if indeed it ever evolved to our present state.
