"Only those live who do good." Count Leo Tolstoy This quote means you'll live longer if you do good because if you're doing bad things you're going through a bad path where probably bad things are going to be happening to you. Example if your doing bad as in smoking then it damages your lungs and etc so you won't live long because you body won't function right. And if you didn't smoke you would live longer for doing good and picking the right choices. If you continue to do good then your going to have a long good life.
