I try to think of it as something that will feel like falling asleep. I don't dread sleeping, so I shouldn't dread dying either.
Isn't the fearsome part of dying just the pain and sickness though? Those things can exist as a chronic state that doesn't lead to death, so I'm not sure it's dying that one should be afraid of...
In some countries like Belgium, unbearable pain that doesn't lead to death is sufficient cause for an individual to be granted assisted suicide performed by medical professionals.
