PRONUNCIATION:It is a shame and a matter debated at large that specialists - whether medical or of other disciplines - are not held in the high esteem that they once were. And yet when you come across a leader and specialist in their field the way they deploy their knowledge, insight and skills remains something to greatly admire and respect. I mean knowledge and experience that transcends sole reliance on interpersonal skills and blinding people with jargon and 'science'. Such are the outcomes of what the specialist brings to the (operating?) table, that it may even seem like a sleight of hand. Not in the sense that it is a trick, but there is an effortless transparency to not only what they achieve, but how they make people - their patients, clients feel. Not just feel, but how these people react and may find themselves.
1. Sleight of hand.
2. A display of skill.
From French leger de main (light of hand), from leger (light) + de (of) + main (hand). Ultimately the from Indo-European root man- (hand) that's also the source of manage, maintain, maneuver, manufacture, manuscript, and command.
If there is a sleight of hand it is in how while a specialist, they can and do cross boundaries. They see and can count the important numbers (evidence) in their discipline, but they know (from some no doubt hard-won lessons) that frequently some of the numbers in the very sequence they need lie outside their comfort zone.
