It's not simply things, but caring and thoughtfulness that count in life

More than 10 years ago, I got a reverse fan letter. I call it that because Sandi Backlund wrote a letter to me and sent it to our son Steve Young, a former NFL player, via a station on which she heard him interviewed. The letter eventually made its way to a very delighted me, who doesnt get much input from readers via snail mail.

Sandi commented on how much she related to a story Steve told of when I went on the field and told a kid not to neck tackle an embarrassing moment in my motherhood history. She related to it because of her concerns while watching her son play rugby. Two of her sons friends were stationed on either side of her to keep her from going on the field (and) doing something similar.

After she contacted me, I began sending my articles to her. She's a good-living Catholic woman from Doylestown, Pennsylvania, and, over the years, she would send back announcements of her activities or her childrens weddings and bits of information. Weve never met face to face, but we are friends.

Less than a year ago, her father came to live with her and she sent emails updating how things were working. Recently she sent out this email, My dad turns 89 on February 18th. There really isnt anything he needs but there is something he likes to do go to the mailbox every day. So I am asking my friends/family to give my dad a birthday card blitz starting February 1st. it would mean so much.

I picked a card, and just before sealing the envelope I thought, Why not stick in one of the football cards Steve signed? I pasted the football card on the left side, then drawing a big word bubble, I put, Hey Sam Serrano, hope your day is happy.

A couple of weeks had gone by when an email appeared from Sandi with a picture of her dad wearing a vintage San Francisco 49ers jacket. I honestly didnt remember him being a fan.

She wrote, Thank you so much for the birthday card, your sentiments and the signed card from Steve. My dad has had this jacket since 1984. What is eerie my dad has been wearing this jacket every day this week and hadnt worn it for about two years.

Sam had gone to the mail one morning expecting nothing, and there was a birthday card from one of his long time favorite players mom with a signed football card inside. He was over the moon. It made my day as well.

The experience reminded me of how little we really need in life to make us happy, especially as we age. We collect fame, fortune and possessions, but its caring and thoughtfulness that count, like a signed football card.

In author Kate Mortons recent book, The Lake House, the protagonist, Alice, ponders a conversation with Ben, the itinerant gardener.

But Ben was different, and he made her see things differently. He had no desire to possess things or to accumulate wealth," Alice thinks as she ponders. "His parents had worked on archaeological digs in the Far East when he was a boy and hed realized then that the possessions people coveted in the fleeting present were destined to disappear; if not to turn to dirt, then to lie buried beneath it, awaiting the curiosity of future generations.

Ben had told her: "All that matters to me are people and experience. Connection thats the thing. That flicker of electricity between people, the invisible tie.

Today with Facebook, FaceTime, email and texting, there are easy ways to keep in touch with others. Press a button on a cellphone, click a mouse and were connected, renewing ties that bind.

Because, as my friend Lindsay Starr Hendrickson and her husband, Blaine, put on their yearly valentine card, Love makes our world go round and round and round and round
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.
