QUIET ZONE Have you ever been sitting on a quiet train, trying to relax before the work day starts, only to have your peaceful moment interrupted by a blast of early 2000s hip-hop that you were not ready to hear this early in the morning?

If this has happened to you, you're not alone. And you can probably agree that not using headphones around other people is a top public offense. But what happens when someone tries to test the public's willingness to forgive this grave offense? As you can see in this video, the results turn out like you might expect with a lot of people annoyed.

The man behind the YouTube channel markbtelevision headed to a few quiet, public spots in Manchester, England, to put his social experiment to the test. To get the best results, he picked out particularly embarrassing songs and "forgot" to plug his headphones in all the way. What follows is a lot of side-eye and laughter from those around him.

At the very least, this video is a good reminder to be considerate of others when you're out in public, but it's also pretty entertaining to watch how different people react in an uncomfortable situation. My personal favorite is the girl at the train station who just looks around scowling until the guy finally turns the music off himself, because I would definitely do the same thing.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
