The dead do not suffer and they do not miss out on anything - because they are not aware of not having the joys of the living. They are conscious of nothing at all (that much the bible got right). So there is no reason to fear being dead; or think that you will be missing out on life when you die. It is the living that suffer from death. It is the living that experience the deprivation of death.
I was dead once before. I was dead for countless eons longer than I have been alive. It was the time before I was conceived. That death didn't trouble me the least bit. It didn't do me the slightest bit of harm.
Live and enjoy life to the fullest while you have it and know that you truly will not be missing out on anything when you die because the unconscious dead cannot experience deprivation.
