Around age 9, many children stop engaging in physical activity just for the fun of it, according to a new Swiss study published in the journal Psychology of Sport and Exercise. Researchers from the University of Geneva (UNIGE), Switzerland, followed 1,200 Geneva students ages 8 to 12 for two years. The team discovered that from the age of 9, the more positive, internally-driven reasons for exercising — it’s fun and good for your health — begin to get replaced with outside incentives: to get a good grade or improve one’s image with other people.
