Defined Chest

The Perett’s book In Your Face: The New Science of Human Attraction reveals that women are strongly attracted to men who sport body that resembles hunter’s physique. So, in addition to the already mentioned strong shoulders, wide back and narrow waist line, chest play the crucial role in determining your sexual attractiveness.
