Lifestyle - interests, opinions, and behavioural orientations of an individual, group, or culture.
Personal lifestyle reflects individual attitudes, way of life, values, world view, and personal identity. Not all aspects of a lifestyle are voluntary. Surrounding social and technical systems can constrain the lifestyle choices available to the individual.
Lifestyle may include views on politics, religion, health, and intimacy.
For example, "green lifestyle" means holding beliefs and engaging in activities that consume fewer resources and produce less harmful waste, and deriving a sense of self from holding these beliefs and engaging in these activities.
