Allan Luks in his book, The Healing Power of Doing Good: The Health and Spiritual Benefits of Helping Others, writes, "Doing good makes you feel good. Concentrating on others makes us forget our own problems and troubles and lifts us out of ourselves... ...The next revolution in health care must be to bring to our awareness the health potential of helping others." He contends that exercise and good nutrition, for all their power to keep us healthy, are not enough for a truly vibrant life.
As Helen Keller said, "I am only one, but still I am one; I cannot do everything, but still I can do something; I will not refuse to do the something I can do."
