Lifestyle is composed of cultural and behavioral patterns that are developed through socialization. Adopting healthy lifestyles promotes health, while new lifestyles in developing countries can lead to major health problems like heart disease, obesity, and cancer. Lifestyle changes are influenced by age, sex, media, curiosity, home environment, peer pressure, and escaping life's tensions and frustrations. Lifestyle diseases are potentially preventable through diet and lifestyle changes and include cancer, liver disease, diabetes, heart disease, kidney disease, and stroke.
