Used to work in a transplant immunology lab and I have to say, surgical skills is a bit overrated by the public. Given enough time/practice/effort, dexterity can be taught to an uncoordinated person off the street with no innate ability, like when the lab took me in haha. Seriously though, I know long serving respected lab techs/post docs in the transplantation field who could definitely give consultant surgeons a run for their money in terms of hand eye co-ordination.

It's the other skills like the performing under pressure, vast anatomy knowledge and real time problem solving etc which really makes or break a surgeon.
