Answer:
People who gave more to others were less likely to die over the course of the study.
Step-by-step explanation:
It has been scientifically proven that those who do volunteer work are happier! Research in the United States has shown that volunteers have a much lower stress burden than other non-volunteers. In addition, they manifest greater balance between work and personal life and have fewer health problems. Based on this, we can conclude that the research done by Stephanie Brown and her friends showed similar results and they could conclude that people who gave more to others were less likely to die throughout the study.
