Ah, I was thinking perhaps you were under China's influence in regards to cremations/burials. My mistake, lol.
If I recall correctly, a film I recently saw, Trash, had a burial-drawer space as sort of an anonymous bank vault/hiding spot.

That's a nice idea for the ashes to be buried with trees so there would be pleasant visiting spots for the living left behind. I've heard that ashes are like a fertilizer for plants so I've told my niece/nephew that they can use my ashes for some plants if they wanted to or whatever.

I also doubt any of us would really care what is done with our bodies/shells when we're dead.
