A business consultant who specializes in the medical trade was telling me how many doctors, dentists, and chiropractors struggle financially.

一位药品贸易的商务顾问曾经告诉我，有许多医生、牙医和按摩师在财务上困难重重。

He had passed his life in estimating people (it was part of the medical trade), and in nineteen cases out of twenty he was right.

他一生都在评估人（这是医疗行业的一部分），二十个案例中有十九个他是对的。
