Two thousand years ago, Hippocrates, the Father of Modern Medicine hit the nail on the head. He said, that if we all had “the right amount of nourishment and exercise, not too little and not too much, we would have found the safest way to health”. Bingo. Obviously then, being a species of great intellect, over the next two millennia we took on his sensible advice, integrating exercise into our daily life and cashing in on the rewards for our bodies and minds. Hmm, maybe we didn’t quite all get that memo. Instead something else happened and physical inactivity grew into the fourth largest global killer in the world (according to the World Health Organisation), with some claiming it takes more lives than smoking, diabetes and obesity combined. Yes, physical inactivity has its price tags. It is linked to the development of chronic health problems like heart disease, type 2 diabetes, obesity, depression, dementia and cancer. It can make us feel bad about ourselves, guilty and frustrated, appeased only with the ever alluring reward of inactivity – comfort, rest and stress-free. Our creaking NHS too gets a bill that would make anyone wince reaching for their wallet – somewhere between £8 and £20 billion per year through both the direct and indirect healthcare costs including that on the economy. Ouch.
