Exercise your brain

While exercising your body is important, it is also important to work out your brain. Especially as people get older and retire they tend to neglect their critical and strategic thinking skills.
The most available way to exercise your brain is to work on crossword, sudoku, or other word and number puzzles that you can find in daily papers or online. An additional perk to doing these puzzles is that they are fun and also reduce stress- obviously.
