Which of these most directly impacts a person's physical health? a. age b. exercise c. culture d. height

the answer would be B exercise

Lack of exercise affects the heart, lungs, blood sugar levels, joints, bones, muscles and mood. It may even play into the development of other heath conditions such as cancer and mental decline. Not exercising affects your ability to control your weight. Despite these negative effects, large numbers of people still do not get regular exercise.
