My favorite is working puzzles.  Elderly people are told to keep their minds nimble by doing a variety of different kinds of puzzles (such as Sudoku and jigsaw puzzles).  It stand to reason that we younger folk can make ourselves smarter by doing various different kinds of puzzles, too. Also noteworthy is that both exercise and rest make us smarter.  Exercise gets our blood and oxygen circulating and rest gives the brain a chance to assimilate all the information it has taken in.   In other words, get up from in front of that screen, go for a workout, and then enjoy a nap.  Then  you can read the rest of this Infographic with a cup of brain-growing coffee!
