I try to walk as much as possible everyday. It seems that walking about 10,000 steps a day will improve one's overall health. The apps (pedometer)
was downloaded from Google play store. Carry it (smart phone) in your pocket when you go for walks and it will record the number of steps you take.
10,000 steps is equivalent to about 7 kilometers.
I heard a friend was cured of his diabetes and high blood pressure just by walking 10,000 steps five times a week. Try it for good health and well-being.
