People can also have blood drawn for their own future use ( autologous donation). In countries that allow paid donation some people are paid, and in some cases there are incentives other than money such as paid time off from work. However, this is reversed during disasters when blood donations increase, often creating an excess supply that will have to be later discarded. Despite the many reasons that people donate, not enough potential donors actively donate. Many donors donate for several reasons, such as a form of charity, general awareness regarding the demand for blood, increased confidence in oneself, helping a personal friend or relative, and social pressure. In some countries, established supplies are limited and donors usually give blood when family or friends need a transfusion (directed donation). Today in the developed world, most blood donors are unpaid volunteers who donate blood for a community supply. Blood banks often participate in the collection process as well as the procedures that follow it. Donation may be of whole blood, or of specific components directly ( apheresis).
