The time has come again.

Upsets will be had, champions will emerge, and for two weeks, madness will reign in offices from coast to coast.

But everyone knows that there's more to March Madness than losing your scrupulously wrought bracket to your seer-like cubicle mate who has never watched basketball in his life.

It's also about pitting college-age youths against each other in gladiator fashion while generating an enormous profit for universities, coaches and media companies.

Here are eight figures you should know about the NCAA Men's Basketball Tournament.

$29,100,000

That's how much the University of Louisville Cardinals profited from their men's basketball team last year. According to PointAfter.com, a website that tracks the earnings of college sports teams, Louisville has the most profitable team, bringing in $45,800,000 in revenues and paying $16,800,000 in expenses last year.

According to Forbes, Louisville's surge in profits came when it started playing at its new arena, the KFC Yum! Center, in 2010. With a capacity of 22,090, the third-highest capacity of college basketball arenas, the team's value increased by 40 percent in two years.

-$3,150,000

That's how much the University of Notre Dame Fighting Irish loses each year from its men's basketball team. Notre Dame is the least profitable team, operating at a loss of $3 million. Surprisingly, many teams don't make a profit. According to ESPN, two-fifths of the teams in the 2014 March Madness tournament were operating in the red.

"There is some truth to the fact that our revenues are not comparable on a per-game basis with the Kentuckys and Louisvilles of the world," Notre Dame athletic director Jack Swarbrick told ESPN. "We don't sell commercial signage, we don't have suites and we don't serve alcohol. So we are limited by the choices we make."

1 in 9,223,372,036,854,775,808

These are the odds of choosing a perfect NCAA tournament bracket, according to Business Insider. In case you're not sure how to pronounce that obscenely large number, it's 9.2 quintillion.

This, of course, is based on filling out your bracket randomly, which isn't usually a good strategy but then again, it is March Madness.

$6,356,756

The salary of the highest-paid NCAA basketball coach, John Calipari of the University of Kentucky. According to USA Today, he got almost a million-dollar raise last year. The average annual salary for an NCAA basketball coach is $1,679,275.

Besides their base pay, coaches also make bonuses. The highest maximum bonus of 2015 was $1,450,000, going to Tony Bennet of the University of Virginia. Virginia is the highest-seeded team in the Midwest Conference this year.

$0

The salary of the highest-paid NCAA basketball player.

There has been much controversy over whether college athletes should be paid a salary. According to the Washington Post, the average college men's basketball player is worth $212,080.

College athletes do usually receive tuition waivers and living stipends, which can amount to as much as $65,000 a year. Money argues that offering a salary of $100,000 would actually disadvantage athletes because, unlike tuition, their income would be subject to taxes. After tax, tuition and living expenses, Money predicts that athletes would have $100 left at the end of the year. Nice.

$1,500,000

This was the average cost of a 30-second advertisement during March Madness TV coverage in 2014, according to CBS. The total ad spending in 2014 was $1,134,000, but that amount has gone up consistently since 2009, so we can expect more spending this year.

Additionally, CBS reports that the NCAA grosses roughly $900 million selling the broadcast rights to the tournament.

$9,200,000,000

The amount of money that will be gambled on the event this year. That number's up $200 million from last year.

According to CBS, some of this money will be bet through legal channels, but the majority of betting is done illegally.

The American Gaming Association estimates that 70 million bracket sheets will be filled out across the country, a number that exceeds the number of ballots that will be cast for Donald Trump or Hillary Clinton in November's presidential election.

$4,000,000,000

This is the estimated losses that American businesses will suffer due to the lack of productivity caused by March Madness.

NBC reports that 20 percent of American workers will participate in office pools this year, and many will be more concerned about monitoring their brackets or watching games than doing their work.

That being said, one financial firm told NBC that "efforts to suppress the 'madness' would most likely result in long-term damage to employee morale, loyalty and engagement that would far outweigh any short-term benefit to productivity."

So enjoy the tournament. Just make sure you're getting your work done too.
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.
