我想他们问我是因为他们相信一个老师应该知道答案，或者因为他们看到我灰白的头发和胡子而相信我的年龄应该有这个能力知道该怎么做。

I assume they ask me because they believe a teacher should know the answers. Either that or they look at my gray hair and beard and believe that my age necessitates my ability to know.

They ask me: what one or two habits should they start with?
