Scientists have it all worked out. To form a relationship, you should be running a marathon on a dangerous route (perhaps in a war zone?), while listening to soft rock and eating chocolate, keeping your body posture “open” and gazing into each passing runner’s eyes (which would increase the danger factor).
Of course, alternatively you might end up with a broken leg, indigestion, and sore ears.
OK, it is very open to mockery, but there is undoubtedly some truth in this, and it goes a long way to explain why in politics and the media (which often run on pure adrenalin) most senior people are on their third or later marriage… But no I promise I’m not going to talk about John Prescott. Wouldn’t do that to you; you might be eating.
