There are many emergency cases in brain surgery, often in the middle of the night, and life is irregular, so it is impossible to estimate the law of life. . Like me: I usually spend a day in the operating room at night and often can't sleep well. Everyone says that good skin comes from sleep. . . So don't choose this. . .

In addition, brain surgery is intense and takes a long time, which is estimated that women's bodies can't stand it. I have a sister at school, and later she became more basic. . . When I started the craniotomy, I drilled by hand. According to my tutor, I exhausted my strength and left no trace on my skull. . . Her extra-brain graduate student drilled this once in three years and failed. . .
