但是，到19世纪末，"疑病症"一词被用来表示“没有具体原因的疾病。”
By the late 19th century, however, hypochondriasis had come to mean "illness without a specific cause."
他没能再具体一点的唯一原因可能是，歌中没有能和“被呕吐物呛住”这种歌词对得上的旋律。
Probably the only reason he didn't get more specific than that was that nothing rhymes with "choked on vomit.
但是这些推动因素没有一个可以长久，具体原因我会在后面大概写一下。
Yet for reasons I will outline later, none of these forces is likely to be permanent.
