There was a moment today when I felt like I was just going to break all of the rules I have ever read on the Internet.

I was going to break the rules I have read about not drinking Coke, not eating carbs and not eating fruit after 4 p.m. I was going to yell at my kids and skip right over the edict to accept myself with no guilt, and I was ready to just go full shame.

Then, in that moment, my shoulder tightened its way up to my ear like a rubber band that was about to snap.

I was sitting in my room, working on deadline, ignoring my childrens requests for crackers and candy, when my older son pointed his Nerf gun at my younger sons head. He squinted his eyes and leaned forward as he pulled the trigger and his younger brother screamed.

I took the Nerf gun away.

We dont point guns at peoples faces, I said. Go to your room.

I considered hurling the Nerf gun across the room to express my frustration, but I refrained. He turned and went, and as he did, he punched his little brother in the stomach. Twang! My shoulder rigged itself even tighter, with a little jolt of electricity buzzing down my arm.

This would be so much easier if I didnt have this deadline Im working on, I thought to myself. Why am I doing this? I have a sink full of dishes. I havent started dinner. My children are going crazy. I need to cool it. Take a shower or something and relax oh, but I cant! I have all of this work to do.

Twenty minutes later, I put the work away and walked into the kitchen, where another child of mine complained about a toy or something. Im not even sure, because as he spoke, I got a zap in my elbow.

Oh great, I thought. Now its spreading. Now I have all of the dishes and dinner and my arm is going to fall off. And I cant even go stuff my face with all of that chocolate in the pantry because its against the rules. This is the worst! What am I doing here!?

I opened a window, and a breeze the kind that smells like dirt, pine trees and impending rain blew in. I love that smell. And as I inhaled, I felt some tension leave my elbow.

I turned on the oven and started washing the dishes. That helped, too. I felt less guilty, less failure beaming from the invisible place in the universe that doesn't look kindly on working mothers. And I started to think, my mother had it worse than this. So did my grandmother Fleeta, who died before I was born.

My mother has worked as long as Ive lived. And working full time was the easy stuff. She added graduate school, part-time jobs and a graveyard shift on top of it for several years. My father worked away from home for a while, too, so then she was handling our household on her own.

Ive always appreciated that my mother has a work ethic that could power a steel mill. At times, in her more stressful careers, Ive urged her to not give so much to her employer, to step back and forget the man for a minute while she takes a vacation or stops working so many hours of overtime without asking for overtime pay. But thats my mother. Shes a hard worker, and I think shes taught me to be the same way, at great sacrifice. I am filled with appreciation.

I called her that night to ask her about those years of hard labor for all of us; those years of little sleep and lots of work. What was that like for her?

I felt like I was on the outside of the family, looking in, she said to me. She talked about sleep deprivation during that time of working an overnight shift and then substituting during the day. Her immune system has never been the same, she said. I thought about my own sleep schedule and recent cold that lasted three weeks. It got better, and we got older. But still, it was tough. And she did it for us.

Fleeta worked full time too. But her financial situation was not as dire as my mothers in those early years. Fleeta had the same will and power but a different freedom to choose her path. I look up to her, too.

I think some of her grit flows in my veins, and I think it combines with my mothers. Together, they power me through deadlines, projects and a day like today.

And, wouldnt you know, just as I hung up the phone, the rubber band feeling was gone.
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.
