> dump me off the end of the pier

That's a quick route to immortality, in my opinion. All my Hydrogen and Oxygen ends up as water that evaporates and falls on crops for people to eat, or ends up in reservoirs for people to drink. My carbon mostly turns into minerals that people will use for all sorts of things, like chalk or drywall. My Nitrogen goes back into the great pool of air people will breathe. Other elements go into sea life that people will eat.

All my atoms get recycled back through every form of life on Earth eventually.
