It's very helpful that people can donate blood freely. It subsidises life and assists individuals in extreme conditions just like on accident prone individuals, surgical operation patients, and other people that have special health complications. Free blood donation means that those hospitals and clinics, where it is taken, will always be famous of enough supply for those in need for such a transfusion as not everybody has friends or family who can help him or her out when the situation demands. There are also some social related benefits that you get when you donate blood; the large blood cell production, screening of general health status etc. Some people may expect to be paid; but free blood donation means workforce directs its energies and funds on helping those in need besides fostering togetherness and empathy.
