A true healthy person has a sound mind and body. Most people only pay attention to their physical health but overlook the mental health. They try to strengthen their bodies by taking different exercises and eating various nutritious foods. But few of them can keep fit because they often suffer from suspense, depression and anxiety. I think we can find a good answer from the nature and the animal world. The Buddhists have benefitted a lot from natural laws. We see the wild animals live simply and well, quite different from the complicated human world. We can also draw some inspiration from the way of life taken by the long‐lived people in the remote areas.
