Cemeteries bring memories of family spread near and far

Cemeteries bring memories of family spread near and far, writes Amy Choate-Nielsen. - photo by Amy Choate-Nielsen
As we drove to the cemetery just before Memorial Day, my children had a lot of questions.

They asked all kinds of questions, like, What is a cemetery? and Will we see dead people? and Can I go into it?

They started talking in very high-pitched voices, yelling over each other, escalating in volume, as they do when they are getting nervous or excited. So we answered their questions and attempted to teach them the rules about cemeteries. We told them to be quiet and respectful, not to run around or climb on the headstones and to be careful where they walked.

I will be so quiet, I will close my mouth so tight, my 4-year-old said. A declaration like that from him is a momentous occasion, and I was grateful that he meant what he said, even if 4-year-olds tend to forget their promises pretty quickly. When he and his sister got out of the car, they tip-toed over to the gravesite with their arms clasped behind their backs, sticking their necks out as they took in the images around them.

Wed never been to a cemetery before.

They walked up to the big granite headstone where their great-grandparents are buried and touched the engraved "Nielsen" with their fingertips, taking it all in.

What does that say? the 4-year-old asked, and we told him the name was the same as his. Its interesting to watch my kids absorb information about death, ancestry and family connections. On the way home, my son said, How come Grandma and Papa dont have any kids?

It is beautiful to see how simple and self-centered the world of a child is, sometimes.

I remember when cemeteries were places filled with flowers and marble and granite. As a child, they were places I went with my parents on occasion to visit people I didnt know. Now I look at cemeteries and wonder where I would want to be buried someday.

Ive only recently realized that burial is a tricky thing, especially for a family like mine, which is spread across the country. There is no central place for us. As a result, I cant remember the last time, if ever, I visited the graves of my family members.

My fathers parents, Fleeta and Irvan, who both died before I was born, are buried in a plain little cemetery in Ada, Oklahoma. I know this because of one of the many available online genealogical resources, a site called findagrave.com. The site holds photos of gravesites from across the country, searchable by name, cemetery and location.

Someone took a picture of my grandparents graves and added them to the site, so I can see that they are buried under simple, long, granite plaques embedded in the grass. My great-grandparents, Austin and Mary, who traveled on donkeys from Texas to Oklahoma so their children could get a better education, are in the same cemetery.

Austins father, Gabriel, who was a Texas ranger and fought with the Confederate army, is buried in the Cold Creek Cemetery in Texas, along with his mother, Keziah Dawson. The photo of Keziahs grave with a record of the year she was born is the only information I have about her.

The only memorable connection I have with a grave belongs to that of my grandmother, Lenore. She died in 2006 and is buried with her first husband, Homer, in a cemetery in Ponca City, Oklahoma. After being separated by death for 23 years, they were reunited.

As for my children, I am glad they can visit the graves of their great-grandparents with their papa and grandma and hear stories about where they came from. One day, my children will touch that memorial and know their ancestors are real.

Perhaps then, they will know the world, and their family, is bigger than they imagined.

But I hope it will still be simple and beautiful.
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.
