Professor Stephen Hawking has issued a chilling warning over one of the world’s biggest killers.
In a minute-long video, he warns that our battle with obesity is one of the most serious issues humans have ever faced.
Professor Hawking says: “I see the world as a whole and I am here to address one of the most serious public health problems of the 21st century.
“Today too many people die from complications related to obesity , we eat too much and move too little.
“Fortunately, the solution is simple, more physical activity and a change in diet, it’s not rocket science.
“And, for what it’s worth, how being sedentary has become a major health problem is beyond my understanding..”
The last line is delivered followed by a long pause as Dr Hawking, who suffers from motor neurone disease, stares at the camera.
A simple message then flashes up on the video, produced by Swedish health organisation GEN-PEP.
It reads: “Physical inactivity is now the world’s fourth leading cause of death.
“Required physical activity per day: Adults – 30 min, Children – 60 min
GEN-PEP is a Swedish non-profit organisation initiated by the Crown Princess Couple that works to spread knowledge and engage both people and organisations in a joint effort to make it easier for children and young people to live a healthy life.
