Typing is certainly a lot more efficient, but discarding handwriting entirely might not be such a great idea. Picking up a pencil and a pad of paper to write out your ideas could aid your thought process and learning ability.
If not just for the level of focus you get from having nothing but a pad of paper in front of you, you might benefit from the actual act of writing by hand. The Wall Street Journal takes a look at how this is an important developmental skill for children, but how it also applies to adults looking to keep their minds active. The idea is that the actual act of writing out the letter takes a little more work in your brain than just typing the letters on a keyboard, and that extra work keeps your mind sharp.
Adults studying new symbols, such as Chinese characters, might enhance recognition by writing the characters by hand, researchers say. Some physicians say handwriting could be a good cognitive exercise for baby boomers working to keep their minds sharp as they age. Studies suggest there's real value in learning and maintaining this ancient skill, even as we increasingly communicate electronically via keyboards big and small.
