2/3. Can science detect sexual attraction? A unique date has unexpected results. Looking for love are 32-year-old Beth, on a mission to find a husband, and Peter, a 37-year-old politics lecturer who can never get beyond being just friends. Our scientists believe they can find them the perfect mate where orthodox matchmaking has failed. The experiments reveal what the ideal man and woman look like, whether opposites really attract and what the most successful dating strategies are.
