So you freak out at the thought of death? Well, do this thought experiment and see if you still hold the same beliefs:
Imagine you will live forever, and everything and everyone around you will too. You go through the same old habits and thinking and reactions every day for the next zillion years. Nothing ever changes and there are no more surprises in your daily life.
Your personality is fixed forever too.
How do you feel about those prospects? If that’s not a description of hell on earth or anywhere else, then I don’t know what would be. Be careful what you wish for!
