Without words, we as a species would be lost, or at least hampered significantly. Not only has language allowed us to reach the stars, (or the outer reaches of our solar system anyway), but it has given us flowery poetry, and fantastic ways to insult each other. On top of all that, learning new words can have the same chemical reactions in the brain as eating good food or having sex. The thought behind this is that the rewarding feeling we get from learning a new word helped us crave more words and allowed language to evolve along with us. This article from Science alert explores the concept in a little more detail. So if you are a little down and are looking for a pick-me-up, pick up a dictionary or read a comic to learn something new and put a smile on your face. And if you really want to have some fun try Wordsmith.org for a daily dose of interesting new words.
