Someone talked about their fear of death in a blog and this was my response:
Life and death are the same thing, ceasing to be one thing and becoming something else. Your five year old self is no more just as you will be no more some day. You have already died many times, you didn’t even notice it.
Every 7 years or so every atom in your body is replaced. “You” did not exist during “your” childhood. What we think of as “I” is a momentary thing that is always in flux. The only way to preserve yourself would be to just stop. To be frozen in place. Don’t fear that you will die some day, fear that you will stop learning and changing and growing and be the same thing forever. That is much worse.
