Actually, personally, I despise all inheritance related laws - I understand the historical origin of them and they did make quite a bit of sense but in this modern world I think the only thing that inheritance does is degrade any attempts we might make at moving more toward a meritocracy.
Then again I was strongly influenced by Longhouse traditions growing up and also feel rather neutral on private property ownership in general.
In keeping with that, I intend to retain the right to disposal of this possession as I see fit.
EDIT-response:
user munk-a: I think I am content to have my body treated just as other property that I have owned in my life. If inheritance laws prohibit inheriting property but permit putting it in a never-dying trust, then I will prefer that my body be treated as such. If all property is transferred to the state upon death, then so be it for my body. I am not anti-social. I merely have this one (apparently peculiar) view on ownership of one's body.
