Giving is good for our health. A wide range of research has linked different forms of generosity to better health, even among the sick and elderly. In his book Why Good Things Happen to Good People,Stephen Post, a professor of preventative medicine at Stony Brook University, reports that giving to others has been shown to increase health benefits in people with chronic illness, including HIV and multiple sclerosis.
Stephanie Brown of the University of Michigan saw similar results in a 2003 study on elderly couples. She and her colleagues found that those individuals who provided practical help to friends, relatives, or neighbors, or gave emotional support to their spouses, had a lower risk of dying over a five-year period than those who didn’t.
