Holistic living

Holistic living is a term used to define simple and spiritual living with moderation in food intake, adequate exercise and positive thinking and attitude to life. Yoga is an example of this concept. In general, it encompasses the following.
 * Simple living ('far from the madding crowd or rat race)
 * Simple food (with less ROS generators - i.e., mostly vegetarian and neither less nor more in amount)
 * Physical exercise (neither light nor heavy - i.e., regular and moderate)
 * Relaxation or de-stressing through various techniques.
 * Positive outlook (optimism) towards life

Holistic health is a subset of this and systems biology tends to explain some of the principles.
