PLAYLAND If youve ever worked a job that required you to watch training videos, you know what a drudgery it can be.

D-list actors drone on stiffly while canned music takes you on a journey to a brain-dead stupor. We wont even talk about the video or editing quality.

But it seems that not all training videos are created equal, especially if you were producing training videos for the fast-food chain McDonalds in the 80s. The creator of this particular video, which I assume is called Clean It, was truly inspired when he created the most upbeat video probably ever made about cleaning.

I cant clearly say if Weird Al Yankovics Eat It came first or if McDonalds Clean It training video came first, but its safe to say that they are neck-in-neck when in competition for the best parody of Michael Jacksons Beat It. The one edge the training video has is the Michael Jackson lookalike in a jumpsuit uniform with shortened hems who is inspecting the cleaning abilities of the employees as they dance in perfect sync.

If working at McDonalds in the 80s is as fun as it looks in this video, sign me up to be a McDonalds employee as soon as we get around to inventing time machines. In case that never happens, feel free to use this song to inspire your kids to do their chores instead of the insipid cleanup song from Barney & Friends.

This video was first posted on YouTube in 2013, but resurfacing classics never go out of style.
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.
