My mom once lost track of me at the zoo and when she found me I was lecturing a man about the difference between dromedary and Bactrian camels. I was about 3 1/2.
In my business if I get too close to you and you die it hurts me. And so you develop a natural inclination not to be close to the patient so that if things don't work out ideally you can still get up the next day and care for the next patient.
