What do you think of the saying "idle people are sentimental"?

"Idle talents are sentimental" I think this is for the elderly to hear, but this is absolutely correct, because one of the things that the elderly like to do most is to drink tea and chat, and then is to play chess, and some elderly people are also short of square dancing. Their lives are not particularly dull, appeared a lot of feelings, because they do not have things to do, so think a little too much.
