What will I need them for? I'm DEAD.
It could save the livings life, and help science. Anyone who doesn't donate them is a little selfish about their corpse. It's a dead body, it's not you. Your consciousness is gone. You no longer exsist. For you theists, you've gone to heaven or hell.
A dead body doesn't need healthy organs, a dying person does.
We can't find cures for deseases due to lack of human tissues/organs/test subjects - you could save lives! Hundreds!
I'm DEFINATLY donating EVERY part of me to science/hospitals (whatever they feel nessiary).
I see you too! XD
