Using the easy-to-remember countdown format shown in the title, this video outlines a strategy that can help teens and adults stay healthy. Viewers learn a daily regimen of the following vital actions: eating five types of fruits and veggies; drinking four glasses of water for cleansing and hydration; enjoying three laughs with friends (aiding mental well-being, lowering anxiety and depression, and even improving the immune system); putting in place a limit of two hours of TV or computer time; performing at least one hour's worth of physical activity; and getting eight hours of sleep. In addition, medical professionals share the facts behind the numbers and offer some practical advice about how to live the countdown.
