Lu Li-cheng, head of research at the Museum of Prehistory remarks that whenever he is drawing up a questionnaire targeted at the old, he is certain to include a question about the respondent's birth sign, because "it is something you don't get wrong. If an old person is unsure of their own age, we can work it out in a moment from the birth sign."
史前博物館籌備處管理研究組組長呂理政表示，他在設計問卷做調查時，對象如果是老年人，一定會加問生肖這一項。「因為生肖記憶不容易出錯，老人家搞不清楚自己幾歲時，用生肖一推算就出來了。」
