We wondered the same thing, Dean. I don't remember exactly, but something like a total professional staff of 10 or 12 people. I do remember the day in treatment team when we realized the vast majority of us were left-handed. I've worked in two additional clinics since then. The percentage of lefties in those clinics was higher than in the general population, but not a majority.
In that first clinic, one clinician had stumbled upon a "lefties" shop in an airport and brought back a coffee mug that I wish I had. It said something like this "Everyone is born left-handed. As soon as you commit your first sin, God makes you right-handed."
Being a sinfully tolerant person, I forgive all you righties, especially those of you who are both shorter than 5' 6" and never mastered "the bump."
