　　In today’s world of modern science and medicine，a more traditional treatment is once again becoming popular-animal friendship．

　　It is now well-known that people with problems such as heart disease or cancer live longer and get better more quickly if they have pets．Keeping pets lowers blood pressure and makes people less worried．Animals are increasingly important in treating older people who have memory loss and other brain problems．These people often feel nervous and upset．Activities with animals help them improve their physical condition and also give them joy，entertainment and loving friendship．

　　Here is a case that shows the benefits of animals．John was a six-year-old mute．．He had no physical problems．He just refused to talk．His older cousin，Ned，had a parrot called Sally，and John used to visit it．When he arrived，Net used to say，“Hi，John!”We all know parrots copy what they hear．After a few visits，Sally began saying“Hi，John!”when John came into the room．Then，one day，John turned to the parrot and replied“Hi，Sally!”Staying with the parrot encouraged John to begin talking．

　　Another use of animal helpers is in schools．In some cases，animals are used to help children with physical or personal problems．In other cases，they are used to teach children to get on and share with others，and even to teach them about animals．

　　If you want to know more about animal helper programmes，you can get in touch with organizations like Riding for the Disabled or do a search under“animal therapy”on the Internet．You don’t have to be an animal trainer or a doctor to join in．
