Rationale: The advantage of a health fair is that it will provide information on all age-related diseases and the prevention of disease, including those with genetic components like colon cancer.

Rationale: A well-documented family history is a tool used by the health care team to make a diagnosis, identify teaching strategies, and establish a pattern of inheritance. The family history should include at least three generations, as well as information about the current and past health status of all family members, including the age of onset of any illnesses and cause of death and age at death. Medications and immunizations are part of the general health history, not specifically the genetic history.
