Theres no one who can love you, annoy you and be your best friend all at the same like a sister can. From old memories of your mom dressing you in matching frilly outfits to recent ones of your crazy adventures together, you couldnt imagine your life without her. Theres a special bond that only sisters have, and only people who have that bond can relate to these seven things:

1. You dont have just one closet (and neither does she)

For better or for worse, sisters are clothing stealers. It is fun to enjoy the benefits of twice the outfits to choose from (that is, if you can get away with). While you rummage through her closet, she might just be searching through yours at the same time.

2. No friendship compares to "sistership"

Best friends are great, but theres just something unique and irreplaceable about that friendship that happens between sisters. Maybe it's something about being being forced to be friends by birth, but the bond the two of you have is strong and awesome.

3. Some of your weirdest moments have been around her

When youre around your sister, you can really let go. You crank up the music and belt out the song lyrics in weird voices, you dance crazily around the bedroom and just act goofy because you feel the most comfortable around your sisters.

4. Despite your long history of sister brawls, you really love each other

I know two sisters who literally gave each other scars from scratching fights when they were younger, but theyre as close as can be. Sisters, especially those close in age, are prone to arguments and fights but that doesnt change the special loving bond you have for each other (even if you really do have battle wounds).

5. Shes your go-to person for venting

Whether you just broke up with a boyfriend or you are dealing with a frustrating coworker, you can always go to her for a good venting session. Wearing sweats and eating ice cream arent necessary, but are recommended for these sister chats.

6. Something feels like its missing when youre apart

That sisterly bond makes you feel somewhat empty when the two of you are apart. Spending time together is the absolute best when youre not together, you miss her more than anyone (and you cant wait until you can get back together again).

7. When you see each other again its just like old times

Siblings grow up, move out and eventually start their own adult lives. That can mean way too much time spent apart from your sis, but when you see her again after all that time, its as if nothings changed. You may both be grown up, but once you are together, you'll still feel like the little girls who grew up together.

Even if your sister ends up living across the country, youll still stick by each others side just like old times. There is no better friend than a sister, and there's no better sister than your own.
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.
