'The Mind at Work' Rethinking Hand and Brain

In this chapter, the author writes about the work of  sugery, physical therapy and teaching. Sometimes compares these works with the work of a waitress, a plumber as well as a hair stylist. The chapter begins with the interview of the author's uncle, which used to be a railroad worker. He earned little money by hard working of labor.
Then the he writes about the work of the surgery. 'Surgery is parallel to carpentry or plumbing or styling hair. In addition to their typical risks and consequences, they are different on many levels; the knowledge base, the number and complexity of the varibles involved, the amount of training required, both the material compensation and the symbolism that surround them.' Instead of getting all the knowledge from the book, these positions all need 'hands-on experience', in order to not only getting each technical move right, but arranging the moves properly and fluidly. They all need the work of brain and hand, but they are distinguished into levels of the work by the meaning terms of the status and incomes, they may be less definitive than we think and may blind us the commonalisties in the way different kinds of work actually get done at the level of immediate, day-to-day practice.
Less description in this chapter, instead, more interview, quotation and more sets of author's thoughts.
