Personal health: Diet and exercise. Two of the most important words in anyone’s life. For a teenager, now is the time to create habits for a life well lived. Helping your teen develop good eating habits and encourage daily physical activity may be difficult for parents. It may require parents and adults to change your bad habits to create a good example. Nothing worse than parental hypocrisy, and it might save your life as well. Sorry for the preaching…no I’m not. It’s for the kids.
