You may be an adult, but you're never too old to solve a few brainteasers. In fact, many adults have found that their advanced age makes it difficult to solve the simplest of children's riddles. Does that mean that old people should stop exercising their brains and give up on mental puzzles? Absolutely not; the challenge will either send you spiraling into a quarter-life crisis, or encourage you to read more to increase your mental capacity. If you're diligent, it's likely that you'll succeed in strengthening your brain power.
After solving these riddles, you'll feel accomplished, and just a little bit younger and more spry (mentally speaking). Even if you can't puzzle them out, at least you can say that you tried; there's no judgment here.
