I swiped a very popular picture, saying that it was an Alzheimer's disease test, and if you can find 3 faces, even if the brain is young. With the mentality of giving it a try, I stared at the picture and studied it.

The first face I found was in the upper left corner, with clear lines outlining the eyes and nose, just like drawing stick figures when I was a child, and I could see it at a glance.

The second face is on the right, you have to squint slightly, and put a few color blocks together into facial features, like putting together blocks, which is not too difficult.

The most strenuous was the third one, which I flipped through for three minutes, and my neck was sore. Later, I accidentally turned the picture upside down and looked at it, hey, the one in the middle, a few interlaced lines actually formed a face! The eyes are two small triangles, and the mouth is an arc, which is too tightly hidden.

She found the first two very quickly, and looked at the third one for a long time, and finally I prompted to "look at it upside down", and she patted her thigh and smiled: "Isn't this like guessing a lantern riddle, you have to turn a corner!"

In fact, this kind of picture is a fun little game and has nothing to do with real medical treatment. But when looking for faces, it's like playing "finding differences" when I was a child, the more I can't find it, the more anxious I become, and I get very proud after finding it. My dad always said that he had good eyes, but after looking at the picture for ten minutes, I finally pointed it out to him, which made the whole family happy.

If you also see this picture, don't be frightened by the word "test", just use it as an activity to exercise your brain. Anyone who can find all three faces, no matter how old they are, is considered a "clever ghost" - after all, even such a deep hidden face can be found out, which is not ordinary.
