What ever??? After I am dead my cells are no longer functioning, My brain is changing from a vibrant living beings to that of basic chemicals proteins and alike. Personally I do not think I would care if you use it to make lampshades, new shoes or a nice leather coat.
I will be dead and no matter what indignity you do to me I do not think I will care much.
Of course there is this side of me which says do not desecrate a body this is the side of me taught by society, fear, and general wish to not die any time in the future. My body is my only link to the world and seeing it destroyed bothers me on a silly illogical level.
I still have not made a firm decision as to what happens to my soul if any yet. I personally believe when the last synaps fires you are gone for the count. No fear, no happiness, no saddness,
NOTHING!
Personally I would like their to be a life after death but I am not convinced that there is a good, bad or indiferent place that we go when we die.
That sucks! I would love to continue forever in some form but I just do not see it logically being likely. Back to star dust we all go.
