While some people may have a tendency to overshare (and perhaps post things that are inappropriate) on Facebook, there are eight things you should never hesitate to post about:

1. Good news

When something good happens to you, it is okay to share it on Facebook! There is a difference between sharing good news and bragging. Sharing good news is letting the world know that something positive, exciting, and life-changing is happening. Expecting a baby, getting a job offer, finishing college...these are things that your friends will want to know and be happy about. Sharing your news on Facebook is a great way of telling everyone without leaving anyone out.

2. Your business

If you've started a new business or are in the middle of a business venture, it is smart to share it on Facebook. Facebook is a great networking tool and can really help spread the word about what you are doing. If your friends get sick of how many times you are posting about your business, they can adjust their own settings to show less of those types of posts. If you are worried about mixing your personal and business life online, consider creating a page just for your business.

3. Uplifting stories

Whether it's your own story, or someone elses you found online, it is always okay to share an uplifting story. Doing just that can instantly change someones mood, bring a smile to their face, or inspire them. These are all things that bring positivity into a all-too-often negative world, and are definitely worth posting about.

4. Things that worked for you

Did you discover a great way to remove stains from clothes? Did this one trick finally get your kid to conquer potty training? Or did you figure a way to actually enjoy doing the dishes? These are all things you should share on Facebook. Life hacks are great things to tell others about; never hesitate to share something that actually worked for you.

5. Personal triumphs

When you have gone through something hard, challenging or difficult, share it with others. Whether it is losing weight, overcoming a hardship, or even recovering from the loss of a loved one, sharing your journey can help someone with their own obstacles. Some of your friends could be going through the same things you are, and you dont even know it. Your story could truly change their life.

6. Photos

It IS okay to share photos on Facebook. If they are photos of you or your own kids, then you can justifiably post them. You should always use caution when posting photos and perhaps limit the amount of photos you post, but you should not feel like you are not able to have pictures of your family online. After all, posting photos and status updates is what Facebook was founded on. All the other stuff came later.

7. Positivity

If you think someone looks really great in a photo, tell them. If you thought the story your friend posted was hilarious, let her know. Dont hesitate to leave a positive comment on someones feed. It is always okay to say something nice, and honestly, it is not done often enough. So share away with your positive comments.

8. Questions

If you have a question or want a poll about something, Facebook is a great forum to use. Curious about what brand of diaper cream is the best? Wondering how to remove nail polish from the carpet? Or wanting a good recipe for a green smoothie? Ask your friends. As long as your question is appropriate, ask away. People are usually eager to share their opinion, and it creates a conversation that others may find helpful.

Instead of just using Facebook to waste time, use these ways to make Facebook a positive tool. Post uplifting news, share kind comments, and spread helpful content to make the world just a little bit better.
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.
