Explanation:

A lifestyle, is a "way of living" that depends on numerous factors and reflects the beliefs, opinions, behaviors and preferences of a person or a group of people. It is constrained to demographic factors, such as location, age and even gender, but it is also constructed by the person's internal characteristics, such as values.
