Very few people get this right: How many pens do you see?

Something that you never get too old for is overcoming challenges.

Puzzles, quizzes, and logical problems really make our neurons move â€“ and itâ€™s not just fun, but also useful. Exercising your mind regularly heals your body and brain.

My mother always solves crosswords for an hour every day, and she claims it keeps her young. I think there is some truth in that. If the brain is healthy, then the bodyâ€™s vitality follows along!

This type of challenges has always attracted me. It doesnâ€™t necessarily have to be deceiving or complicated stuff. A math problem or test is fine â€“ the important thing is that you enjoy yourself and race against your friends to see who overcomes the challenge first.

This clever picture (below) that I found on the Swedish Facebook page Technology Palace earlier today â€“ got my brain working full steam. To solve it, you have to concentrate and focus all your senses.
