perhaps this person sees past all of that “oh look ive done 2 neck whacks, 2 parotidectomies, and this and that and blah blah blah, i believe im a real surgeon” bs and just wants to get down to business, since he knows once he gets out, the only thing he’ll do to put food on table will be teeth and titanium (no shame in that at all). so why waste what’s left of his energy and youth learning something he will never do outside, instead of spending his time & energy currency laser focused on perfecting his craft, on that which he will use the most.
maybe not everyone has that “passion to really help others” nor even a passion for actual surgery and just wants to do good work and earn a decent living, again absolutely no shame in that at all.
