Want your kids to be good with money? Here are 4 financial lessons you need to teach them... - photo by Troy Martin
Its never too early to start teaching your kids how to handle their money.

In fact, it's an especially important topic to teach your kids at home. While most high schools require students to take macroeconmics, classes like personal finance are rarely required or even available.

So, you can't really rely on the schools for this life lesson. Its up to you to show your children how to spend their money wisely, how to avoid crippling debt, and how to make sound investments.

The following four money lessons will help your kids grow into financially responsible adults:

1. Tie allowance to chores

Who knows? Maybe your kid will grow up to be a lottery winner and wont need to work to provide them the funds they need to pay all their bills.

But, more likely, they will need to work to afford goods and services. To prepare them for this mindset early on, never give your kids allowance just for the sake of giving them an allowance. Instead, make them earn it by taking out the trash, mowing the lawn, etc.

Its also wise to assign a dollar value to each individual chore and allow your kids to make more money in a given week by doing more chores. Doling out more rewards for harder work will help instill in your children the initiative theyll need to rise through the ranks of a company later on in life.

2. Keep savings in site

A piggy bank is cute, but it makes the amount of money your kid is saving up a total mystery. Let your child see exaclty how much is in their little money jar. Empty out a big mason jar or other transparent container and put it in a place your child sees daily.

3. Get them a bank account

Once your child becomes a teenager, its time to graduate from that mason jar to an actual bank account. The earlier kids understand how banking works, the more savvy theyll be with finances in the future.

4. Teach by example

If youre up to your eyeballs in debt and blow through hundreds of dollars a week on unnecessary expenses, its going to be all but impossible to teach your child to to be financially responsible.

The best way to get your kids to do what you want them to do is to teach by example. Live within your means, stay on top of your credit, and do extensive research before you make a major purchase. There's a good chance your kids will do the same when theyre older.

Teaching your kids these four lessons as they grow up will save you (and them!) some serious financial headaches in the future...you might even raise the next Warren Buffet! At the very least, youll produce someone who can manage their finances and live comfortably.
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.
