EXPLORE NEW FIELDS
Puzzles are a fun way to keep your mind sharp, but some people are looking for more serious intellectual stimulation. A good way to give your mind a regular workout is to learn something new. Love Paris? Take up French. Interested in the Civil War? Bone up on 19th-century American history. Like computers? Learn how to code. Developing knowledge in new fields helps keep you connected to the larger world, and wrestling with new ideas is a good way to exercise your brain. There are many ways to explore new fields for little or no money. The library and Web are obvious starting points. For more formal pursuits, many colleges and universities reduce or eliminate tuition for older students.
