Learning how to do something new can benefit your brain by challenging it and keeping it engaged. Plus, learning new things can be a lot of fun. You could, for example, sign up for a class where you learn to paint, cook, or dance. Or you could check out a new fitness class at the gym. Or, how about heading to a batting cage or the driving range, or downloading a language app on your smartphone? Pick something you think you might enjoy and work it into your schedule.
