A few months ago, my son Boston found a bag from a cute boutique called Over the Moon.

Can I take this? he asked about the bag with the store's name on it.

Puzzled, I nodded, and he ran downstairs with the bag. A little while later, he showed me what he had written on the front:

Dear Dad, I love you (arrow) Over the Moon and back!

He was so excited to give Brad his Fathers Day gift and had saved it all this time.

In years past, we have given Brad and the grandpas cards about them being superheroes, great golfers and barbecue masters. Weve praised their dad-ness by expressing thanks about them being hardworking and great leaders.

But this Fathers Day, I want to express my gratitude for the fathers in my life for simply being there.

Growing up, my dad worked hard. He is a psychiatrist and was often on call. He rarely took time off for vacations, and worked many weekends. But he was almost always home for family dinner. I loved waiting for him at the bottom of the stairs and jumping up into his arms as soon as he walked through the door. I used to sit on his feet, which sported nice but worn-out socks with a cracked heel usually poking through the bottom, and ride around our slippery wood floor. He would lead our family in a dinner prayer and always made it a point to compliment my mom on her home-cooked meal.

Its funny how its the little things that stick out to me years later: him turning on News Radio in the mornings as he drove me to school, him loudly cracking up at a joke from a TV show, him choosing to floss his teeth or blow his nose at the most awkward times, the sound of his click-y toe popping as he walked upstairs in the middle of the night to check on us, and him waking us up to ask us if we were asleep.

My dad still has a way of making everyone feel like they are taken care of. He is generous to a fault and always ready to give advice or predict the end of a movie. Its funny how even now I revert to my inner child when Im around him, asking him to drive me places and help me with things we both know I can do for myself.

Nowadays, I wait by the door for my husband, Brad, and all but throw myself into his arms as soon as he comes home. I watch our boys sit on his feet, and smile as he walks them around our slippery wood floor. I wonder if they know how lucky they are to have a dad that takes time after a full day of work to build Lego cities or wrestle with them on the beanbag. Finding a man like my own dad was paramount for me when I was dating, and even though my husband and my father are very different in many ways, they are similar in their love and loyalty to their family.

This Fathers Day, I want to say thank you to fathers, fathers-in-law and father figures who are making the time to just be there. They are real-life heroes.

We love you Over the Moon and back.
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.
