My best friend has never said a word to me

Lessons of friendship, love and more we can learn from man's best friend. - photo by Steven Hummer
Ive known Daisy for five years, and she has taught me lessons about loyalty, happiness, friendship and love that Ill never forget.

Daisy is a wonderful companion. She never complains about what is being served for dinner, and shes never forced me to go to the fabric store or sit through the movie Pride and Prejudice (both are my kryptonite).

Instead, shell happily sit beside me as I binge watch Netflix or cheer on my team in a football game, and shes never asked me if I thought she looked fat.

Daisy is my best friend, and shes never said a word to me because Daisy is a golden retriever.

What is it that makes a dog mans best friend, and what lessons can we learn from our four-legged friends?

Show enthusiasm for the people you love

Whenever I walk through the front door, Im always greeted by a whine. Then a blur of golden fur, (that coats my living room and clothes dont get me started) as my dog runs circles around me and leans up against me putting all of her weight on my legs and her gentle eyes that can only be described as kind, look up at me.

My dog is just happy to see me. It doesnt matter if I have been gone for five seconds or five hours, Im always greeted warmly. I cant recall a time when my dog wasnt pleased to see me.

Unlike my dog, I cant say Ive always been pleased to see people at my door, like the pushy salesman or shady-looking people whove come to buy an item I had apparently placed for sale online when I have no memory of ever posting such a thing (thanks for the practical joke, my brothers friends).

Everyone needs a friend

Dogs arent as picky when choosing their friends.

Weve all had our bad days when the car wont start, the bills pile up, and we argue with our families.

But dogs dont have bad days, and they dont hold grudges. Dogs find joy in the simple things in life.

Whenever I grab the mail key, Daisy will bound to the front door, tail wagging and a big doggish smile forming on her face because she simply loves going to get the mail.

She loves going for walks, running at the park, sitting next to me while I read or just being in the same room as the family.

There is always time to think of others

Dogs can teach us about selfless service.

The organization "Canines with a Cause" rescues dogs from kill shelters and trains them to become service animals for veterans suffering from PTSD.

After theyre trained, the dogs are paired with a veteran depending on the individual's needs as far as temperament, personality, size and other factors.

Program director Cathy King said, Were kind of like a dating service between people and dogs getting them setup with their perfect match.

Provide constant support

Websters Dictionary defines loyal as, having or showing complete and constant support for someone or something.

Relationships come and go, friends drift further apart through the years (though we still insist on seeing what our friends from high school are up to ten plus years later via Facebook), but its comforting to know mans best friend is there showing us complete and constant support.

These friendly, loyal, caring companions may never say a word to us, but actions speak louder than words, and we can all learn something from them.
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.
