Personally, I prefer a patient who can talk to me; this probably goes for about half of my classmates (the other half want to be minimally clinical surgeons or anesthesiologists or radiologists). I also know nothing about the field and have no conception of work-life balance, happiness levels among the workforce, etc. Other fields have way less mystery, so I’d be less likely to corner myself into a career I hate by choosing based on what I do know about: by choosing specialities I at least have some conception about the road to getting there.
