i dunno about malays and indians, but superstitious chinese arent keen in leaving the earth with an "incomplete body", si3 wu2 quan2 si1.
Never heard of it before
It should not be much of a problem, as the number of people with these thinking are minimal.
Organ donation needs more awareness, do you guys know what's the hotline for organ donation in Malaysia?
Start by donating blood at blood donation drives, they visit some collages sometimes.
Blood donation is pretty much painless, and you just lie down there and relax until it's done. Afterwards you feel really satisfied that you've accomplished something. That's what I felt anyway. I strongly recommend any able body to do their part for society, as we are nearing the holidays, blood requirements rise as well.
