Nurses, especially ER nurses, sometimes deal with drunks and get stabbed.
Nursing, imho, must be a passion, it can't be anything else and still provide exceptional medical care and humanity. Without passion...one provides "adequate" care, and "Oh yeah, you're still alive. Now I have to empty the bedpan again.
Hats off to the nurses out there...and police, fire, sanitation workers, etc. All the people who make our cities and country great.
