A Few Riddles Per Day Keeps the Dumb Away
Most people had a lot of riddles when they were children. They probably had little kid's books filled with easy riddles, or their teachers would share a riddle with the class and then everyone would put on their “thinking cap” and talk to each other and try to solve it. But then as we get older, that kind of thing stops. It becomes all about serious subjects like math and science, and much of the fun is lost.
It turns out that doing brain teasers such as riddles into adulthood can help improve mental “quickness” and prevent IQ loss over time. It turns out your elementary school teachers knew what was good for you! The best way to take advantage of this principle is to spend a few minutes each day doing a riddle or brain teaser.
It doesn't matter what time of day you do it, although in the morning seems to work best for most people since they can then think about the riddle throughout the day as they go about their normal tasks.
Other people will ponder it during their drive or train ride (or walk) to work in the morning, and if they get stuck they can ask a coworker for help (kind of like “group learning” in elementary school!).
