WHO chose 14 June as the day to recognize the millions of people who save lives and improve the health of others by donating blood. The Day highlights the need to regularly give blood to prevent shortages in hospitals and clinics, particularly in developing countries where quantities are very limited. The annual event focuses on motivating more people to become blood donors. It demonstrates how health systems and policy-makers work to make blood transfusions safe and accessible to people worldwide. Every year, countries throughout every region of the world organize a huge variety of events and activities to celebrate the day, from football matches to free concerts, and from mobile blood donation clinics to monumental decorations. WHO and partners have decided to focus the 2012 campaign on the idea that every one of us can become a hero simply by giving blood. The everyday hero responds to an immediate need, whatever the conditions, despite inconvenience, putting the needs of others above their own. Voluntary blood donors come from all walks of life, all regions, backgrounds, religions and ages. By choosing to donate blood without getting paid, these individuals commit an \"heroic\" act, a gesture of human solidarity with the power to save lives. Some of them do so dozens of times over several decades.
