Grace goes to the doctor. The doctor tells Grace that while her chronological age is 24, her physiological age is 30. What factors could account for this discrepancy?

Answer:

Grace's advanced physiological age is a sign that her physical health has diminished since a healthy person should either have the same chronological and physiological age or a lower physiological age. The factors that could cause her physiological age to be greater than her chronological age include, among others, a poor diet, sedentary lifestyle, great amounts of stress, chronic illness, and other negative health factors.
