my grandfather is over sixty.  he looks younger than his real age.  he was a policeman before his retirement.  he has a positive attitude towards his later years of life. he does physical exercises every morning.  he can read books without wearing glasses. he is so strong that he is able to lift heavy things by himself.

　　he loves children very much. every monday afternoon he is invited to a nearby school to tell stories to the children about the life and work of the policemen. all the young pupils love him very much.
