However much you studied...your "hand" was distinctive - as personal as your voice or laugh. But as typewriters proliferated after World War II, handwriting gradually became less important. Authors typed their manuscripts and students typed their school papers. As telephones became universal, letter-writing virtually disappeared. In the e-mail age, most people seldom need to write more than a grocery list or a short note, or sign a check. It's not only kids; many who formerly wrote fluently and neatly have forgotten how.Link, Via, Via.
"Sign a check"? Do you still write checks? I wrote my last check a couple years ago, and never got around to ordering new checks. I pay all my bills online. Don't you?
