Priority #1
If my body can be salvaged in any way to help other human beings, by all means salvage away. Women and children first.
Priority #2
If my body can be used in any way to help the planet, by all means, utilize it to help the planet.
Priority #3
There isn't one, because once I'm dead, it isn't about me anymore, and if I'm living my life according to altruism, it should never be about me anyways.

Thought provoking post.
Thanks.
