All the good times we had, and will have, with anyone or anything ever will totally annihilate into nothingness.
No. They will still have happened. You will still have experienced them. You can only really ever experience whatever is happening to you now. If there is only nothingness after death, then you will not experience it.
Make the most of your life in the way it make sense to you. That could be having more shared laughs with loved ones or dedicate it to saving the critically endangered purple-spotted pygmy shrew.
In short: You will experience your life, you will not experience "the great void of death".
Min er ikke klar endnu.
