Robert Lynd is amazed at the efficiency of human memory. Modem man remembers telephone numbers, names of film stars, cricketers, football champions and even notorious murderers. He remarks wittily 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 extraordinary memory power. In some matters, the memory is less than perfect, causes could be psychological. We tend to forget things we don’t wish to remember.
For example, many people forget to take medicines. Medicine needs to be taken before / after meals. Robert Lynd remarks that chemists make a lot of money because people tend to forget to take medicines. It aggravates the disease and people are forced to buy more and more medicines. Most people forget to post.letters. The author himself would not trust his letters to be posted by others. The author himself never remembered to post letters entrusted to him. He had to apologise for the unposted letters kept with him for long. Likewise, the author forgets his walking sticks often.
