Vivienne Parry

How much exercise do we need? Is eight hours the right amount of sleep? What is the 'average' libido? When does 'normal weight' become 'overweight' or 'obese'? And how do doctors decide if what's going on inside someone's head is normal?

When it comes to our health, what constitutes 'normal'? Who decides, and where do they draw the line? Is 'normal' the same for everyone? And if you don't tick the box marked 'normal', do you need treatment or are you simply different? In these 34 episodes, science writer and broadcaster Vivienne Parry attempts to answer these questions, and work out what 'normal' means with regard to our bodies and minds.

Talking to doctors, patients and a wealth of medical and scientific experts, she considers issues ranging from mental health and physical wellbeing to fitness, child development, parenting and sex.

Over the course of eight series, Vivienne explores topics including cancer, blood pressure, giving birth, dyslexia, drinking, depression, ageing and autism. As she tries to build up a picture of what normality looks like, she discovers that in defining 'normal', we create 'abnormal' - and that in reality, 'normal' is anything but.
