An Age reduction programme that can make you live and feel up to 26 years younger

Although your chronological age is fixed, your biological age can be years younger or older than what your date of birth dictates. How we look after ourselves - our diet, our lifestyle, our stress levels - can all contribute to our biological age. Age is not just a chronological measurement; it's the rate at which our cardiovascular and immune systems decline. Now we can halt, and even reverse, the ageing process.

RealAge calculates the effect of more than 100 different health behaviours, including diet, chronic smoking and sleep patterns on your biological age. But more importantly with tests and questionnaires, it shows you how to develop a lifestyle which can improve, and reverse, your own ageing trajectory.

This book includes 44 scientifically proven steps that delay ageing. Dr Roizen and his team have consulted over 25,000 medical studies in their research.
