I had a friend in high school who got squeamish at the sight of blood, or at least that’s what we all thought. She went on to become a surgeon. Turns out, it’s the idea of people being in pain that got to her. Operating on someone who’s out cold was absolutely fine even if they’re gushing blood all over the place, because they can’t feel it.
I used to work at an engineering firm and one day I saw one of the engineers leave at like 2pm on a Wednesday and he was like, “Bye, see you next week!” He had been busting his ass to finish a project and already hit his 40hrs for the week.
I was a temp at the time but needless to say, I jumped at the chance when they offered me a real job.
