I do like the idea of donating my body to a university to help train doctor, but I honestly don't really care, whatever my friends and family feel will help them grieve and move on I guess.
However I would like to be cremated, and then using the carbon to make pencils to be given out at my funeral, except for my skull which will given to whoever slays me, and my femur which will be given to my dog to do with as he wishes.
