Volunteering has a long tradition in many communities.
- B
Many volunteer organizations rely on regular contributions of time.

- Dcheck_circle
Adults randomly assigned to volunteer two hours a week for a semester reported significantly greater gains in measures of purpose and well-being than otherwise similar adults assigned to spend the same time on solitary leisure activities.
