As far as I've seen in my life, surgery is the handcraft discipline of medicine. Surgeons, while they operate, do their job with the attitude of a car mechanic. Even if the surgeon does not like you when they see you outside of the operation room and treat you harshly, in the OP room they just do their routine (hopefully carefully) and you're but another body which needs to be fixed at that moment. If surgeons let emotions guide them at their job, they couldn't do that job for years and years. They need this distance because they have the lives and health of their patients in their hands - literally. So they see them as bodies, as matter, as clumps of tissues while at work. And usually they want to do a good job.
