把这一句，留给此刻的你
Medical men all over the world having merely entered into a tacit agreement to call all sorts of maladies people are liable to, in cold weather, by one name; so that one sort of treatment may serve for all, and their practice thereby be greatly simplified.
世界各地的医生们只是心照不宣地把人们在寒冷的天气里容易得的各种疾病都用一个名字来称呼;因此，一种治疗方法可以为所有人服务，他们的做法因此大大简化。
