Any activity that uses brain power is good to do, especially if you enjoy it. But research has shown us that participating in a variety of activities that use multiple cognitive skills can push our processing speed and accuracy along at a faster rate than just doing the same activity over and over. So it makes sense to find multiple activities—just like we are advised to do for our bodies—that enable us to work on different parts of the brain or on using multiple skills simultaneously.
