Of all the indignities inflicted upon left-handed people (scissors, wristwatches, coffee mugs, guns, corkscrews, baseball, can openers, measuring cups, computer mouses, fishing rods, snowblowers, lawnmowers, circular saws, chain saws, lawn chairs, violins and most musical instruments, ballet, figure skating ....) when I first encountered this type of desk upon graduation to the junior high school level I was the most livid.
I have no trouble using a lot of those left handed. Coffee mug, baseball, lots of great south paws, my last strike in bowling was left handed, made every one there mad, lawnmower requires both hands, just pull the cord with the right, lawn chair, can't say about the last two, but a cork screw, righty tighty lefty loosy, same, same both hands! Of course, I am ambidextrous, translation, I can write equally illegibly with either hand! Sure has come in handy riding motorcycles, flying airplanes and working as a mechanic. I sure fill sorry for all you mono hand people!
