No one really knows how and why people change as they get older. Also, no theory sufficiently explains all the changes of the aging process. Aging is a complex and varied process that varies in how it affects different people and organs. In fact, even in one person , different organ systems “age “ at a different rate.

    At a certain point in our lives our body systems will begin to weaken . It may become more difficult for us to see and hear. The slow change of aging causes our bodies to lose some of their ability to bounce back from disease and injury. In order to live longer , we have always tried to slow or stop this change that leads us toward the end of our lives.

   Many factors decide our health . A good diet plays an important role. The amount and the type of exercise we get are another two factors. Our living condition is yet another. But scientists studying the aging problem want to know: Why do people grow old? They hope that by studying the aging medical science they may be able to make the length of life longer.

    There is nothing to be afraid of as the old age comes. Many consider the later part of life to be the best time for living. Physical activity may become less, but often we get better understanding of the world and ourselves.

    What we consider the old age now may only be middle-aged some day soon. Who knows ,with so many advances in medical science happening so quickly, life length may one day be measured in centuries ,rather than in years!

One day not too long ago the employees of a large company in St. Louis, Missouri returned from their lunch break and were greeted with a sign on the front door. The sign said: “Yesterday the person who has been hindering(阻止)your growth in this company passed away. We invite you to join the funeral in the room that has been prepared in the gym . ”

       At first everyone was sad to hear that one of their colleagues had died, but after a while they started getting curious about who this person might be. The excitement grew as the employees arrived at the gym to pay their last respects. Everyone wondered: “Who is this person who was hindering my progress? Well, at least he’s no longer here!”

       One by one the employees got closer to the coffin and when then they looked inside it they suddenly became speechless. They stood over the coffin, shocked and in silence, as if someone had touched the deepest part of their soul. There was a mirror inside the coffin: everyone who looked inside it could see himself. There was also a sign next to the mirror that said: “There is only one who is capable to set limits to your growth: it is YOU.”

       You are the only person who can revolutionize your life. You are the only person who can influence your happiness, your realization and your success. You are the only person who can help yourself. Your life does not change when your boss changes, when your friends change, when your parents change, when your partner changes, when your company changes. Your life changes when YOU change, when you go beyond your limiting beliefs, when you realize that you are the only one responsible for your life.
