In Mars and Venus Collide Gray looks at how the pressures of our modern work-oriented lifestyles are putting added stress on our relationships and making it harder and harder for them to work out long term. Men and women deal with stress in different ways and their different needs often lead to misunderstandings; miscommunication and resentment – in short, Mars and Venus collide.Bringing Mars and Venus into the 21st century, Gray explores the different ways men and women approach their problems and offer a clear, easy-to-understand programme to bridge the gap. For example, a man's reticence when he is under pressure is actually a natural way for him to rebuild much needed stress-reducing testosterone from his depleted system. Equally, a woman's need for conversation and support when she is overwhelmed stems from a hardwired need for cooperative activities to rebuild her own stress-reducing hormone, oxytocin. It's not that he's just not into you – he needs to fulfil a biological need. And it's not that she means to pester you – she is also biologically driven.
