At the moment,
humanity faces a major challenge and millions of lives are in danger. As a cosmologist I see the world
as a whole and I’m here to address one of the most
serious public health problems of the 21st century. Today, too many people
die from complications related to overweight and obesity. We eat too much and move too little. Fortunately, the solution is simple. More physical activity
and 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.
