Exercised and health
Physical exercise is good for us, and is said to decrease the risk of coronary heart disease, type 2 diabetes and cancer of the colon. It is curious that in any list of reduced risk whatever the pre disposing element is , cancer of the colon is on the list.
Walking even at 3 miles / hour increases respiratory and cardiac measures and blood glucose concentrations. Most of all there is an enhanced feeling of well being.
Everyone who has had 3-4 year old children knows that it is essential to give them a run about to burn off some of the exuberance of being 3-4.
There is no reason to believe that this requirement becomes unnecessary as one grows older.
30 minutes of moderate exercise on most days of the week cannot be other than good.
Walking is such an exercise, gardening and cycling are also good as is swimming
