Whether people are healthy or ill when they are older is strongly influenced by the health habits they develop as young adults.​

Research has consistently shown that the lifestyle and health habits people adopt during their young adulthood have a significant impact on their health outcomes later in life. This includes behaviors such as regular exercise, healthy eating habits, avoiding tobacco and excessive alcohol use, and managing stress levels. By establishing healthy habits early on, individuals can reduce their risk of chronic diseases and other health problems in their later years.
