Don’t worry, it’s just there until your bofy decomposes and is eaten by the worms. Then over enough time, the wood will rot away leaving your skeleton which in turn will slowly fossilise and then when the sun expands in 5 million billion years time, the earth will be scorched and then obliterated and your remnants will return to the stars until the universe keeps expansion until no atom of matter can interact with another and the universe fades out.

Just enjoy the absurdity of it all or get believing in a sky daddy. Either way you won’t have to worry about the forever box.

Edit: whoops, was off by 1 3 orders of magnitude.
