Few people realize that environmental pollution and some behaviors like physical activity and tobacco smoking can affect their health by "turning on" or "turning off" certain genes through a process called "epigenetic modification." This study will develop and test strategies for communicating about epigenetics that are understandable and that do not increase ethical, legal or social issues (ELSI).
