What Rosie says is all true. I'd like to add that volunteering is certain to be an agreeable experience because no one would ever be asked to do something for which they lack the aptitude or inclination and even small deeds are hugely appreciated by residents who can't do them themselves. And let's not overlook the importance of simple human contact: for someone whose family is far away or passed away, a friendly greeting with a big smile has a big impact. Volunteering simply makes you feel good. I recommend it.
