<h2>According to John Adams, there is no way to preserve personal liberties without general knowledge.</h2><p><strong>This quote may seem a little crazy, but when you think about it, it makes perfect sense.</strong></p><p>Those who have a passion for general knowledge are always eager to learn about the state of the current world in relation to history, and about the state of their location in relation to other parts of the world.</p><p>Those who do not care about general knowledge are great at following the passage of time just like a piece of wood follows the river. The piece of wood could get lucky and built into a bridge, but it could also follow the flow down a rocky waterfall. They have less control of their life and are at the mercy of others.</p><p>And what better way to build passion about the world than through crosswords. Crosswords are not only a fun way to pass time, they also improve problem solving skills, communication skills and vocabulary. It's a good way to improve teamwork if solved in a group. For older people, crosswords keep the mind active and sharp........</p>
