People who are between midlife and old age are looking for another round of service with the same motivations that young people have—to give back, to have an adventure, to acquire experience, and to gain credentials and credibility.
Businesses in the same industry can be loath to work with competitors. But—as shown by the creation of All For Good, which aggregates volunteer opportunities from nonprofits all over the country—sometimes working together can result in more good than harm.
Most opportunities for service involve painting schools or serving food. But many Americans have skills—accounting, design, communications—that would be incredibly valuable for nonprofits and would make their volunteering more rewarding.
