    When we think of a generation gap we usually think of conflicting tastes in music, or pastimes. But now the generation gap is handwriting. After one teacher in Tennessee discovered that she had students who couldn't read the assignments she was writing on the board, she posted it on the Internet saying handwriting should be taught in schools.

    Opponents claim that handwriting has become out of time in our modern world. Typed words have become a primary form of communication. Once a practical kill handwriting is no longer used by the vast majority of Americans. It is no longer taught in schools, and some claim that the time that it would take to teach it could be put to better use, for instance, by teaching the technical skills.

    But even in today's world there are still plenty of reasons to pick up a pen and apply it to paper. Many American institutions still require original signatures, for instance, signing for a registered letter and buying a house. And original signatures are much more difficult to forge(伪造) than their digital counterparts. There is also strong evidence that writing by hand is good for the mind. It activates a different part of the brain, and improves fine moving skills in young children. People also tend to remember what they write by hand more than what they type, and the process of writing by hand has been shown to stimulate ideas. Besides, studies have shown that kids who write by hand learn to read and spell earlier than those who don't. Not to mention, handwriting is pleasing, as is evidenced by the fact that no one has ever typed a love letter. And handwriting remains popular as an art form.

    Yes, we live in a modern world, but we live in a modern world that is based on fundamental values.
