Q: Do Gentlemen Really Prefer Blondes? A: Marilyn Monroe, Scarlet Johansson and Gwyneth Paltrow would be happy to know that they do. During the Ice Age, when even cavemen were in short supply, the blonde woman really did get her man - simply because her light coloured hair made her stand out. Plus scientists have recently discovered that natural blondes have higher oestrogen levels. In short, golden (preferably long) hair shouts : 'I am young, sexy - and fertile' to every member of the male species within a few miles. Q: When's the best time to seduce my man? A: Your other half will definitely get more possessive and more attracted to you when you're ovulating and at your most fertile. You'll spend time on your make-up and choose next day's outfit before you go to bed. Your lips will be fuller, and your skin will be radiant because of the high levels of oestrogen being pumped through your blood. But don't get carried away by how sexy you feel. You are also more likely to be unfaithful during this period and your boyfriend is also likely to run away with another equally fertile member of the female species. Q: How do I get him to change his wild lifestyle? A: Get pregnant. Shocking but true. Fathers have lower testosterone levels than single men which means that they are more easy-going and less confrontational, they take fewer life threatening risks, and they are far less likely to have an affair with the leggier, skinnier blonde from the office.
