If you can't stop looking at pretty women, keep this in mind. From the smallest baby, to the prettiest woman, to the old fat man down the street, human beings are all made out of the same stuff; blood, veins, muscle tissue, guts and fat--all covered over with a thin layer of skin. Keep that in mind and it will help you turn away from looking at what you shouldn't. It will also help you to be humble before G-d, for that is really all we are.
