During a routine office visit to his family physician, Harlod expressed a concern to the doctor regarding his wife Ethyl's loss of hearing. Doc explained to him that some hearing loss is normal as a result of aging. But Harold stated that he thought it to be severe.

If no response, move forward 10 feet at a time until he gets a response. That afternoon as Ethyl was in the kitchen preparing dinner Harold decided to conduct the test. He went down the hall some 50 feet away and calls out to Ethyl. "Ethyl, what's for dinner tonight?" No response from Ethyl. Harold then proceeded to move forward 10 feet at a time per doc's orders, calling out to Ethyl, "Ethyl, what's for dinner tonight?"
