Every man in this world wishes to live long and nobody wants to grow old. But this desire of man is never fulfilled. Growing old is a process that begins with birth itself and continues throughout the life.

          When the child is born, all the parts of his body are tiny. All the biological processes continue with a fast speed. As man grows older, biological changes take place in the body. These changes cannot be prevented. Old age is the culmination of these biological changes. Do you know which are the biological changes brought about by old age?

          With the advancement of age, biological processes slow down, due to which the strength and sensitivity of man also diminish. This is because of the fact that the rate of production of proteins in the body decreases. Changes in the enzymes are also responsible for aging process. With reduced physical activity, man starts losing weight, his eye sight becomes weak and hair go grey. All these are the signs of the old age.

         In old age, changes occur in all the cells and tissues of the body. The cells of kidneys, liver and intestines become weak. Blood vessels become old and consequently they are not able to carry blood and other nutrients adequately to all parts of the body. As a consequence aging increases. As the age advances, eyes, ears, skin, teeth and digestion become weak. Blood circulation becomes irregular. Finally life comes to an end.

          The rate of growing old may be different with different people but old age spares none. This is a definite biological change which cannot be prevented. However, with the help of nutritional food, pure environment and proper exercises, early onset of old age can be prevented.
