One form of social prejudice against older people is the belief that they cannot understand or use modern technology. Activities like playing computer games, going on the Net and downloading MP3s are only for the youngsters. Isn’t it unfair that older people enjoying a computer game should be frowned（皱眉）upon by their children and grandchildren?
