Many devote almost half of their time to physical exercises, which, of course, is very good for your body, but you should not forget about exercises for the brain. The best exercises are puzzles and math problems.
For you, we prepared an entertaining puzzle that only the smartest can handle. Try to do it in 20 seconds.
Look at the picture and immediately say what you saw on it, and then take a closer look and understand that at first, you didn’t see everything!!! At first, it may seem to you that this is an old man, but look even closer and you will find the correct answer!
This puzzle is not so easy. It takes ingenuity to figure it out. Some probably guessed to turn the picture over and find a dog chewing on a bone on it!
