⟩ A man got up at 9 a.m. He became so engrossed in his newspaper he did not have time to go out and shop as he had planned. At 11 a.m. he went for a flying lesson. He carefully followed all the instructions given to him by his instructor until he came in to land. He then ignored his instructor and crashed the plane killing them both. The accident would not have happened if he had gone shopping, which just goes to show how important shopping can be. Why should this be so?
The man had neglected to buy a new battery for his hearing aid. The old battery failed just as he was coming in to land and he therefore did not hear his tutor's crucial instructions.
