Lifestyle is the typical way of life of an individual or group. The characteristics of a lifestyle are expressed through attitudes, behaviors, and interests. Lifestyles are shaped by various factors, such as genetic endowment, upbringing, and interpersonal relations within a family. Alfred Adler used lifestyle as a metaphor to explain why people behave and think the way they do. The first use of the term was in 1922, but Weber's writings weren't translated into English until Adler's. The word lifestyle is a broad concept that encompasses different elements of human behavior, consumption, work, and leisure. It is often interconnected with nationality, subculture, and self-identity. One view of lifestyle focuses on habits, beliefs, and values. A common factor among cultures is cultural heritage. Often, the lifestyles of two or more countries can be very different. A person's lifestyle is a reflection of the values and attitudes of the people living in that country. A lifestyle is composed of social practices that are closely tied to a person's personal preferences. Affluent people often own a car, while lower and middle class people rely on public transport. In addition, affluent individuals often seek out exotic international destinations and go on vacations to enjoy themselves. Generally, the definition of lifestyle refers to an individual's way of life. This approach focuses on a consumer's preferences and habits, while recognizing the role of public and private media in shaping their lifestyles. Although this style is more relaxed, it does require the skills of a photographer. Lifestyle photography is often an amalgam of staged and authentic interaction. The photographer must know how to interact with the talent and move them in a fluid manner. Many lifestyle photographs involve children and their parents or siblings. It is very rare to have a scene without children together, but if this is possible, try to make it as natural as possible. Taking pictures during this style of photography is a valuable experience for both the photographer and the subject. Earlier studies of lifestyles focused on the analysis of social structure and individual positions. Behavioral economist Thorstein Veblen broadened the view and argued that people adopt specific'schemes of life' and consume conspicuously in order to differentiate themselves from others. These activities are often considered as part of a self-identity project. The need to express oneself through these activities creates a desire to consume particular consumer goods and to make their choices visible to the world. The lifestyle of wealthy people is very different from the lifestyle of the poor. Some ethnic groups practice consanguinity, which causes genetic disorders. Reformation of this lifestyle can help prevent genetic diseases. Furthermore, Iran has one of the highest rates of medication use among countries. While the use of medication is common, a significant portion of Iranians opts to use it without a prescription. The most commonly used medications are pain relievers, eye drops, and antibiotics.
