This is one of the amazing fact that I realized after watching the series at National Geographic Channel. Did you know that your brain is super smart? So smart that it helps to “adjust” a little bit of what you are about to see.

What did you see on the picture above? Did you see a darker shade of grey on the box above as compared to the below? If yes, you are normal.

However, if you use your finger to block the line that separates the two box. What did you see? Amazing right?

Do it yourself and let me know the results 🙂
