1. You can't think if you're dead. 2. Therefore you'll never think you're dead (and be right about it) 3. Therefore the subjective experience we will all have is that we never die. ("afterlife" is not death, just more life) As time goes on, we will always find that we're still alive - because there's no alternative. That seems encouraging to me. Am I missing anything? Of course other people might see us die and we might actually die, but the subjective is the only thing that matters.
