Zugzwang is a German word which translates to "compulsion to move." There comes a time in chess, when moving your piece is fatal to your game, and, not-to-move is not an option that you might otherwise exercise.
Has the Gordian knot of data -- and the compulsion to add more data, sans reflection, sans a salient matrix, sans logic, sans common sense, sans clinical judgment, sans practically everything except unthinking tribute to mathematical numbers and statistics, in the pursuit of a puzzle wrapped in a mystery and placed inside an intellectual riddle besides a scintillating/shimmering mirage -- that is pathognomonic of migraine research, sealed the fate of migraine and its researchers both to zugzwang?
In medicine, and medical research, how you start determines where you will end!! Sometimes, you start in African safari, stare at huge turds, and end-up with your name linked to lymphomas for perpetuity--not in a laboratory.
Is it too late already? Will data indeed overwhelm logic and common sense quintessential to genius? Or will inspiration clear the deck and ring the bell?
