Due to medical problems, some people just cannot donate blood.
So dun ask why there are people who refuse to donate. Even you give
them money. But....
.....if lets say your company's HOD or CEO ask the staffs to
come forward for a blood donation exercise ( some co even asked
blood bank to park their blood truck in their premises ) you can
see many many people line up for that. Not only for donating blood
but also to impress their boss. 
Today
major papers even mention that our local blood suppy can only last
for few days nia.
