I've lived with two medical doctors, both of whom referred to me, with a doctorate in particle physics but now a software engineer, as the 'real doctor'.

Which for me really highlights the point that, despite using the same title, the word doctor implies two completely different but equally important types of experience.

In Chinese, the common words for medical doctor (大夫 and 医生) are totally different from the other type (博士).
