I carry an organ donor card too but wouldnt donate my body for research. I know that's completely irrational considering that I wont be aware of what's happening to my body (hence the definition of the word 'dead') but I dont like the thought of medical students treating it disrespectfully.
Also like all other deeply religious people, they believe that god will not leave someone to die in a hospital without support, unless of course it was their time to go.
Absolutely! People bury their heads in the sands - 'Allah Kareem' - God is merciful! Only, he's not, and shit happens, but they dont want to prepare for it because they'd rather not face it and just continue to put their trust in God, like children. And in doctors, as if they can do anything without the resources.
