Physical Danger
You're dealing with sharp instruments, but they really shouldn't be pointed in your direction if you're using them correctly. You'll need to be more worried about picking up infectious diseases (but then, that's why you're wearing the mask and gloves). Sadly, a lot of surgeons didn't know enough when AIDS hit. Surgeons cut themselves all the time during surgery and…bad things happened.
Don't forget the long-term effects of being on your feet all day, including Tired Feet Syndrome. You may be referred to an Ottoman Specialist.
