Its a noble work. Don't say it is BUSINESS. Do you know how many people are survived thru CCT(Chiranjeevi Charitable Trust) ? You will realise when you really need BLOOD and you don't get on time. BTW the blood received freely will never be SOLD, it is given for FREE or some charge for maintainance charges. Try to appreciate the Good Work. If you can't, just keep mum. Where are you from ? Looks like not human planet.
