Faces - old faces, new faces. Pulling faces and painting faces. Discovering that looks are more than skin-deep. See the woman who has at least 60 faces and find out how a face can get you anywhere. So prepare to face the fact that you may not be able to face yourself in quite the same way again. Meanwhile - Think of a Number: two faces - father and son - when the father was 31, the son was eight. Now the father is twice as old as the son. How old is the son now ?
