A day, I came across an old friend in a museum.                     
My friend was in his sixties. Therefore, he looked so                       
young. I asked him how he stayed young.                            
He told me take exercise was a good way                             
to keep health, such as, having a walk.                                  
His office was 2 miles far away from his home .Every day                    
he went to work on foot instead taking a bus. He                             
also gave me some other suggestion to be in good                             
health. He thought how fun it was to do sports.                         
Heard what he said, I decided to take action.
