Upon opening my email, I saw a message from my son's fourth-grade teacher reminding parents that the class would be doing its final mile run to complete the series of timed miles as part of a PE unit it was doing.

As I had done the time before, I made plans to attend so that I could cheer on my son, Ace. I even made sure my husband came home for lunch so that he could watch him run, too.

As we got to the schoolyard, we saw no other parents there, just lines of fourth-graders making their way out to the field.

My husband turned to me with a look of embarrassment.

Were we supposed to be here? he asked.

Right then, Ace's teacher waved at us with a smile, which made my husband feel more at ease.

As the run got underway, my husband and I watched as Ace remained back in the middle of the pack, then slowly inched his way to the front. We were amazed at his stride and how natural of a runner he was.

Each time he passed us, we couldn't help but cheer and shout words of encouragement.

With one lap to go, he was nearly stride for stride with another boy in his grade, which prompted us to cheer louder for Ace. And with only a few meters to go, he was able to edge out the boy to come in first.

When I went to congratulate my son, I saw child after child crossing the finish line, exhausted and with no parent to meet them with words of praise and encouragement. I began to think that perhaps I didnt belong there. Maybe my presence gave my child the edge and without it, the playing field may have been more even.

Just as I was about to resolve never to attend another PE performance again, Ace came up to my husband and I with a smile that said it all: He was grateful for our support.

Right then, I realized that our presence there did give Ace the edge, but it was no different than a parent attending a school play, a math-athon or a spelling bee.

I began to feel sad for the kids whose parents weren't there to cheer them on to a great performance. Had there been more parents, I know there would be more kids trying harder to beat the clock.

More than that, it would send a message that physical education is just as important as any other subject a message that has sadly been lost in many of today's schools.

So, to you parents of school-age children: Support your children in PE. They need it more than you think.
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.
