Walk Walk! Fast walk!! (Be your own doctor)

Walking all the way and making yourself pyshically healthy is something a important advise said by doctor. But what is the actual funda behind?

Hope the side image gives all the clear picture of what is going to be in the article.
It is all accupuncture it deals with. When you fast walk your foot completely gets the pressure it needs for regulating other parts of the body. But when you jog or run your toes doesn't mostly rest on floor and also the amount of pressure to be exerted for a period is not achieved. When your are fast walking the purpose is satisfied.
So what is really a aerobic fast walk should be like. You should wear a soft footwear which should distribute the pressure equally to all the areas without damaging your foot wiht over pressure or roughness. The duration everyday you have to walk (corresponds to distance)and the amount of pressure (corresponds to how fast you walk) will count for your better health.
