The Importance of 
keeping your legs strong. When we are old, our feet must always remain strong.
When an elderly man ages, he is not afraid of his hair turning white or his skin is sagging or wrinkled.
Among the signs of longevity, summarized by the US magazine "Prevention", "strong leg muscles" are listed in the top order
Do not move for two weeks, leg strength has decreased by 40 years
 A study from the University of Copenhagen in Denmark found that both old and young, during two weeks of inactivity, leg muscle strength weakened by a third, which is equivalent to 40-50 years of age.
 As the leg muscles weaken, it will take a long time to recover, even if you do rehabilitation later.
 Therefore, regular exercise is very important.
 The whole body pressure is on the legs.
 1. The foot is the pillar bearing the burden of the human body.  50% of a person's bones and 50% of the muscles are in the two legs, the largest and strongest joints and bones of the human body are also in it.
 "Strong bones, strong muscles, and flexible joints form the "iron triangle" that carries the most important load on the human body."
 70% of the activity and expenditure of energy in one's life is done the two feet.
 Did you know that when a person is young, his thighs can support a car!
 2. The foot is the center of body transport.
 Both one's legs have 50% of the nerves of the human body, 50% of the blood vessels, and 50% of the blood flowing through them.  It is the large circulatory network that connects the body.
 Only when the feet are healthy then the conduction channel runs smoothly, then people who have strong leg muscles will definitely have a strong heart.
 3. Aging starts from the feet
 As a person gets older, the accuracy and speed of instruction transmission between the legs and the brain decreases, unlike when they were young.
In addition, the so-called "bone-fertilizing" calcium in the bones will sooner or later be lost, making the elderly more prone to fractures.
  Fractures in the elderly easily trigger a series of diseases, especially fatal diseases such as brain thrombosis.
 You know: 15% of patients will even die within a year of a fracture!  !
 Exercising the legs, it is not too late even after the age of 60 years

  Although our feet will gradually age with time, exercising our feet is a lifelong task.  Only by strengthening the legs, can one prevent further aging.
