Sometimes patients, after being diagnosed and given only one to three months to live, may continue living a healthy life three months later with the help of performing virtuous deeds such as liberating animals or undertaking a long life practice. When the patients go for check-up again, doctors find the symptoms all gone. This has happened in Tibet, China and other parts of the world. It is not hearsay or a fairytale but a fact, which somewhat validates the existence of causality.
