Found this on the internet - thought you guys would like it.

Studies show that volunteering is really good for your health, so even if you make no $$$ from it, you'll feel better and be happier.

Evidence of volunteerismís physical effects can be found in a recent study from Carnegie Mellon University, published this month in Psychology and Aging. Adults over age 50 who volunteered on a regular basis were less likely to develop high blood pressure than non-volunteers. High blood pressure is an important indicator of health because it contributes to heart disease, stroke, and premature death.
The story is at the Harvard Medical School and stuff.
