Yes however, I'm torn between either donating my organs or donating my body to science.
My thinking is I could maybe help save a couple of lives if my organs are in a decent enough state, although with my life style they probably wont be, or maybe my body could be used as a cadaver to train new doctors possibly saving a lot more lives.
Even if its not used for training doctors my thinking is that even a small amount learnt from the use of my body has got to help somewhere.
