Lifestyle is the interests, opinions, behaviours, and behavioural orientations of an individual, group, or culture. The term was introduced by Austrian psychologist Alfred Adler with the meaning of "a person's basic character as established early in childhood" for example in his 1929 book "The Case of Miss R.". The broader sense of lifestyle as a "way or style of living" has been documented since 1961. Lifestyle is a combination of determining intangible or tangible factors. Tangible factors relate specifically to demographic variables, i.e. an individual's demographic profile, whereas intangible factors concern the psychological aspects of an individual such as personal values, preferences, and outlooks
A healthy or unhealthy lifestyle will most likely be transmitted across generations. According to the study done by Case et al. (2002), when a 0-3 year old child has a mother who practices a healthy lifestyle, this child will be 27% more likely to become healthy and adopt the same lifestyle. For instance, high income parents are more likely to eat organic food, have time to exercise, and provide the best living condition to their children. On the other hand, low income parents are more likely to participate in unhealthy activities such as smoking to help them release poverty-related stress and depression. Parents are the first teacher for every child. Everything that parents do will be very likely transferred to their children through the learning process..
