There are many benefits to being a reader--you're never bored; you have a great vocabulary; you do well on the SATs . . . But the main one is all the important stuff you learn.

72% of women having a good hair day have more spring in their step.
Good job, Prevention editors. I feel both smarter and healthier now that I know that.
