Volunteering is generally considered an altruistic activity where an individual or group provides services for no financial gain. Volunteering is also renowned for skill development, and is often intended to promote goodness or to improve human quality of life.
Volunteering may have positive benefits for the volunteer as well as for the person or community served. Many volunteers are specifically trained in the areas they work, such as medicine, education, or emergency rescue. Others serve on an as-needed basis, such as in response to a natural disaster.
