There are reasons to volunteer at any age, but for older people, there are some very significant ones. Research shows that seniors who donate their time to a good cause enjoy greater life satisfaction. They also have better mental and physical health than their peers who don’t volunteer. A study conducted by the Corporation for National and Community Service revealed that older adults who volunteer at least 100 hours a year are able to maintain an active and independent lifestyle. They also experience longer life expectancy and fewer incidences of depression.
