″What is the point of delaying death if we don’t enhance life?” asks Dr Peter Attia. It’s a question to which the former cancer surgeon-turned-management consultant and now bestselling author devotes his life. The secret, says Attia, is to focus less on how long we are living and more on how well we are living: to increase what he calls our “healthspan”.

According to Attia, most of us are living longer, but rather than enjoying our later years, many are spending them in ill health or pain, or grappling with what he calls the four horsemen of chronic disease: cancer, diabetes, dementia and heart disease.
