Robert Lynd is amazed by the efficiency of human memory. Modem man remembers telephone numbers, names of film stars, cricketers, football champions and even notorious murderers. He remarks with jest that man does not forget a single item of his clothing. No one forgets to shut the door when leaving the house. The institution of family survives in modem cities because ordinary people have efficient memory power. In the ordinary life, man remembers almost everything he is expected to remember like birthdays and Valentine’s day. He remembers appointments for dinner and lunch. He remembers what the weather was in a . long-part August. Not even one in thousand forgets, simple things like switching off lights before going upstairs or a single item of dressing. Almost everybody remembers to do the right things of the right moment till it is time to go to bed.
