Have you ever wondered what all blue-eyed people have in common, aside from their stunning irises? It turns out, this rare eye color comes with a fascinating genetic history – and some unexpected superpowers.
While brown eyes may be the most common around the world, blue eyes are the second most popular. But the story behind this unique trait is anything but ordinary. In fact, evidence suggests that all blue-eyed individuals can be traced back to a single ancestor who lived between 6,000 to 10,000 years ago.That’s right – every single person blessed with those mesmerizing azure orbs shares a common genetic mutation that “turned off” the ability to produce brown pigment in the iris. This ancient switch has left blue-eyed folks with some surprising advantages…and disadvantages.
One of the most well-known quirks of blue eyes is an increased sensitivity to light. While those with darker irises have more melanin to protect the delicate tissues at the back of the eye, blue-eyed individuals lack this natural shield.
The purpose behind those mysterious black cables on the road

If you ever see black cables stretching across the road, you had better know what it means. I had no clue… Check comments.
While on the road, chances are you have spotted the black cables on the road.
However, although they are common and perfectly safe to run over, most people don’t have a clue about their purpose.
These rubber cables, that are stretched across the road, serve the purpose of gathering data about the traffic. So how do they work? When a vehicle crosses over them, it causes pressure which is recorded and transmitted to a counting device.

This information assists transportation agencies in keeping track of traffic flow, vehicle speeds, and volume, which is essential for urban planning, road maintenance, and safety upgrades, ultimately affecting the decisions on traffic management, road expansions, and the positioning of traffic signals or speed limits.
Rubber cables are often positioned in low-visibility areas to avoid drawing attention and to minimize any interference with traffic. This approach guarantees that the collected data is as precise as possible, representing typical traffic conditions without the effects of altered driving behavior.
