Meatpie, you should will your body that guy who plasticizes dead people and displays their carcasses sliced and diced for the public to see. You would get to travel the world and I might actual have the opportunity to see what you look like, albeit a bit altered. I read that a plasticized cadaver can last a very long time. You would have a form of immortality.
Another option lately is some kind of an environmentalist burial plan. Instead of burying your body in a casket. You are buried in a kind biodegradable sack over which a tree is planted. You become fertilizer for the tree and, for the romanticist, you become a part of the tree for a very long time.
Of course, your ashes could also be used as a fertilizer. You could make someone's lawn a bit greener or help a tomato be a bit more tastee. It's like recycling yourself back into the food chain.
Scattering the deceased's ashes is a ceremonial act that represents setting the soul free. It been done for thousands of years. More or less, for those who are not that spiritual, it's also an act of closure.
