There are fundamental public health problems, like dirty hands instead of a soap habit, that remain killers only because we can’t figure out how to change people’s habits,” said dr. Curtis, the director of the Hygiene Center at the London School of Hygiene & Tropical Medicine.

伦敦卫生与热带医学院卫生中心的主任 Curtis 博士说："存在一些根本性的公共卫生问题，比如不养成用肥皂洗手的习惯而只是脏手，这些问题仍然是杀手，仅仅因为我们无法找到改变人们习惯的方法。"

Nature gave us lips to conceal our teeth," ran one popular Victorian maxim, alluding to the fact that before the birth of proper dentistry, mouths were often in a shocking state of hygiene.

有一句流行的维多利亚时代的格言说："大自然赋予我们嘴唇，是为了遮掩牙齿，" 这句话暗示了在正规牙科诞生之前，人们的口腔卫生状况常常令人震惊。

A flashing set of healthy and clean, regular 'pearly whites' was a rare sight in Victorian society, the preserve of the super-rich (and even then, dental hygiene was not guaranteed).

在维多利亚时代社会中，一口洁白、干净、整齐的牙齿是罕见的景象，只有超级富有的人（即使如此，口腔卫生也并不一定有保障）才拥有。
