1. Why can not we laugh at the photo of ID cards?
We know that staying serious and not smiling in the photo of the card or passport application is MUST, but not all of us know why. The reason is related to biometric scanners launched in 2005. They only recognize someone's face if it stays neutral, as this prevents misuse of the document.
2. Why are passports never orange?

3. Why people hate it when they hear their voice
Sure you heard your voice recorded somewhere, you made a strange face because you do not like how it sounds, but why does this happen to us? Because changes in the recorded voice cause our expectations to not be met and as a result we are disappointed.
4. Why are tennis balls yellow?
Before they were green, they were black or white, but the problem is that with both of these colors it was hard to distinguish on the TV screen. Therefore, it was decided that the tennis balls would be yellow, to be more visible to the audience.
5. Why do dark circles form under the eyes when we are tired?
After sleepless nights or busy work we notice the famous bags under the eyes. According to doctors, these circles become visible because lack of sleep or fatigue slows blood circulation around the eye area. As a result, the capillaries found there swell and make the area around the eyes appear darker.
6. Why are school buses and taxis always yellow?
Because this color attracts attention faster than others. Among the many objects you would spot something yellow even in the dark.
