I’m left-handed and writing with a pen almost always ends up being a messy affair. In the West, we write left to right, making my left hand drag the ink along and smudge the page. Even with a pencil, my hand tends to cramp as a left-handed person must write inward across the page. I’ve often envied right-handed people who can gracefully write outward across the page like a violinist with his bow extended to caress the sweet high and low notes.
The computer is an equal-opportunity instrument, though I imagine if I researched the origins of the QWERTY keyboard, I’d find it was designed not only for the slowness of mechanical typewriters, but also for the prominent right-handed population. Even though I prefer writing my first draft in longhand, I often start on the computer.
