One of the most precious gifts we can give is time. This is particularly the case when a person is young and healthy. Even the young can be generous with time. We have volunteers who spend a year, sometimes in a foreigh country, helping others.
We have some older members of our community who like to write e-mails. One of them sends me 5 or 6 a day. Most of us who get these e-mails don't read them. I also have friends who send long jokes. I seldom read them.
