The old people should avoid various unfavorable environments and mental stimulations. They should do their best to avoid the environments and scenes of the death, funeral, disaster, grief and depression. The revelrous, pretty and coquettish, frivolous and obscene occasions are not suitable for them. They should cultivate the happy and pleasing temperament according to the personal character and interest like tranquilizing the mind to sit quietly, chatting with friends, watching fish beside the pond and walking through the forest to listen to the bird's singing. This can make them content with their lot in life and is beneficial to health and longevity.
