Think you can spot someone with anxiety in a crowd?
The disorder, which touches 18 percent of American adults, is one of the most common mental health issues in the world. It can affect your teachers, your loved ones, your baristas or your neighbors.
But its prevalence isn't all there is to know about the mental health disorder. Take a look at the infographic below, which shows just how many ways anxiety can affect someone's life. If the facts prove anything, it's that anxiety sufferers are certainly not alone.Infographic Credit: Tower of Power

For the first time in 50 years, microphones attached to a NASA-launched student balloon have captured strange hisses, crackling sounds and faint whistling.
Researchers aren't sure what the sounds are but have some guesses: Signals from a wind farm under the balloon's flight path, crashing ocean waves, wind turbulence, gravity waves and vibrations caused by the balloon cable, according to Live Science.
The balloon, which flew above New Mexico and Arizona on Aug. 9, 2014, was part of High Altitude Student Platform, conducted by NASA and the Louisiana Space Consortium and designed to foster student excitement in aerospace careers.
Daniel Bowman, a graduate student at the University of North Carolina at Chapel Hill, designed and built the equipment, Live Science reported.
Bowman told Live Science he was surprised at the complexity of the "infrasounds," which are very low-frequency counds that cannot be heard by human ears but can be speeded up to make them audible.
Strange noises captured on audio
During its nine-hour flight, Bowman's balloon reached a height of more than 123,000 feet (more than 23 miles), a record altitude for infrasound experiments, according to Live Science. The region is "near space" -- above where airplanes fly but below the 62-mile marker at the top of the stratosphere.
Bowman said he hoped the results would help revive interest in atmospheric infrasound, which peaked in the 1960s as a way to detect nuclear explosions.
"There haven't been acoustic recordings in the stratosphere for 50 years," he told Live Science. "Surely, if we place instruments up there, we will find things we haven't seen before."

A team of astronomers peering deep into the heavens have discovered the earliest, most distant galaxy yet, just 670 million years after the Big Bang.
"We're actually looking back through 95 per cent of all time to see this galaxy," said study co-author Garth Illingworth, an astronomer at the University of California, Santa Cruz.
"It's really a galaxy in its infancy ... when the universe was in its infancy."
Capturing an image from a far-off light source is like looking back in time. When we look at the sun, we're seeing a snapshot of what it looked like eight minutes ago.
The same principle applies for the light coming from the galaxy known as EGS-zs8-1. We are seeing this distant galaxy as it existed roughly 13.1 billion years ago.
EGS-zs8-1 is so far away that the light coming from it is exceedingly faint. And yet, compared with other distant galaxies, it is surprisingly active and bright, forming stars at roughly 80 times the rate the Milky Way does today.
This precocious little galaxy has built up the mass equivalent to about 8 billion suns, more than 15 per cent of the mass of the Milky Way, even though it appears to have been in existence for a mere fraction of the Milky Way's more than 13 billion years.
"If it was a galaxy near the Milky Way [today], it would be this vivid blue colour, just because it's forming so many stars," Illingworth said.
One of the many challenges with looking for such faint galaxies is that it's hard to tell if they're bright and far, or dim and near. Astronomers can usually figure out which it is by measuring how much that distant starlight gets stretched, "redshifted", from higher-energy light such as ultraviolet down to optical and then infrared wavelengths. The universe is expanding faster and faster, so the further away a galaxy is, the faster it's going, and the more stretched, or "redder", those wavelengths of light will be.
The astronomers studied the faint light from this galaxy using NASA's Hubble and Spitzer space telescopes. But EGS-zs8-1 seemed to be too bright to be coming from the vast distances that the Hubble data suggested.
To narrow in, they used the MOSFIRE infrared spectrograph at the Keck I telescope in Hawaii to search for a particularly reliable fingerprint of hydrogen in the starlight known as the Lyman-alpha line. This fingerprint lies in the ultraviolet part of the light spectrum, but has been shifted to redder, longer wavelengths over the vast distance between the galaxy and Earth.
It's a dependable line on which to base redshift (and distance) estimates, Illingworth said - and with that settled, the team could put constraints on the star mass, star formation rate and formation epoch of this galaxy.
The telltale Lyman-alpha line also reveals the process through which the universe's haze of neutral hydrogen cleared up, a period called the epoch of reionisation. As stars formed and galaxies grew, their ultraviolet radiation eventually ionised the hydrogen and ended the "dark ages" of the cosmos.
Early galaxies-such as EGS-zs8-1 - are "probably the source of ultraviolet radiation that ionised the whole universe", Illingworth said.
Scientists have looked for the Lyman-alpha line in other distant galaxies and come up empty, which might mean that their light was still being blocked by a haze of neutral hydrogen that had not been ionised yet.
But it's hard to say with just isolated examples, Illingworth pointed out. If scientists can survey many galaxies from different points in the universe's very early history, they can have a better sense of how reionisation may have progressed.
"We're trying to understand how many galaxies do have this line - and that gives us some measure of when the universe itself was reionised," Illingworth said.
"One [galaxy] is interesting, but it's when you have 50 that you can really say something about what galaxies were really like then."
As astronomers push the limits of current telescopes and await the completion of NASA's James Webb Space Telescope, set for launch in 2018, scientists may soon find more of these galaxies even closer to the birth of the universe than this new record breaker.
"You don't get to be record holder very long in this business," Illingworth said, "which is good because ultimately we are trying to learn about the universe. So more is better."

Two photographs of a "dead alien" were unveiled at a big money event last night - and immediately dismissed as fake.
A series of 'UFOlogists' appeared at the Be Witness meeting last night to reveal images of an extraterrestrial who supposedly crashed to Earth during the infamous Roswell incident in 1947.
The images were found by former journalist Adam Dew, who reportedly turned down interviews with magazines that wanted to cover the story because "they were not offering any compensation".
Alien or mummy? A screenshot of the slide, which has not been released He claimed to have taken steps to verify the pair of alien snaps and said Kodak experts had dated the film to 1947.
But the rest of the world has not had the chance to test the rigour of his methods, because high resolution images of the alien are not yet available.
They are likely to be sold through his production company Dew Media alongside a documentary about the discovery of the slides.
The photos were supposedly found in Arizona, hidden in a collection of snaps owned by oil geologist Bernard Ray and his wife Hilda Ray, who have both died.
Nick Pope, a researcher who headed up a UFO investigation wing at the UK Ministry of Defence, told Mirror Online he was "underwhelmed".
"It could be a model, or it could simply be a fake image, dressed up to look like a Forties slide," he said.
"The motivations for hoaxing are complex. Some hoaxes are money-making scams, but sometimes it's just a desire to say 'we fooled the world'.
"I can understand why the UFO community is disappointed and conspiracy theorists are probably already claiming the whole thing was a government plot, designed to discredit the subject and
make it look ridiculous."
After the photographs were revealed, UFO spotters immediately took to Twitter to share screenshots of the snaps using the hashtag "#BeDisappointed".
