Ok
so we go from a song speaking about the happiest day of my love is the day that I die
to speaking our wishes for when we die XD

I for one either want to be burried with my own headstone or with something which is not possible at this time.
some researchers created something like a large bio-degradible egg where we get burried in and get your fave tree planted on top
basically youll become the tree's earth
changes cemeteries to ancient forests like fields
ill take a sakura tree
