Walking therapy in the mountains

Why do we like to walk? Why did we like it so much again, precisely in the age when travelling with other means of transport is easier and more accessible to everyone? Why so many books on the subject? Why the blooming of festivals that promote it? What is so special about this being the simplest thing that every human being, from the age of one year, does with absolute normality? Why walking, which for thousands of years has been necessity/fatigue/risk, has become unexpectedly attractive/transgressive/innovative for that segment of the world’s population more attentive to sustainable progress, people certainly well-off and educated? It is true that preventive medicine is making a battle horse to combat the sedentary diseases and stress that prevail today. The ten thousand passes per day, equivalent to an hour of walking, that is 5 or 6 km., will have to become the horse of battle of every family doctor who respects. In the USA already many doctors refuse to prescribe drugs, for example those anticholesterol, if patients do not make balanced diets and a healthy walk die. Many studies have now shown that simply walking we produce a good dose of those substances, serotonin and endorphins for example, which give us well-being.
