Let the elderly living alone feel no longer lonely, then let the elderly to develop a hobby, such as stargazing, not, square dance do handmade reading and so on, shooting video is also OK ah!
People are young and not lonely because some busy, if the elderly always have something busy will not feel lonely. A lot of old people like to square dance, mainly because there is a companion to have fun.
Don't like the square dance of the elderly can discover their own young like but did not have time to play the fun, I believe that not much cost can be full of fun.
