The following scene is not uncommon outside any public hospital. Professional blood donors hang around blood banks. They are in search of needy persons, usually relatives of patients. These relatives often borrow money to pay the 'mediator' or donor in order to escape donating blood for their own relations. Wrong notions about donating blood are responsible for this state of affairs. Lack of knowledge coupled with the dire need for blood make a man 'buy' blood at any cost.
