The way you breathe is unique to you, like a fingerprint.

 Doctor listening to patient breathing

Although you do it tens of thousands of times a day, you probably rarely even notice when you breathe in and out. So it may come as a surprise to learn that the way you breathe is as unique as your fingerprints. Research has shown that individual breathing patterns — including the timing, volume, and rhythm of chest movements — can be used to identify people with up to 97% accuracy. Over the course of a day, the way you inhale and exhale creates a distinct respiratory signature as recognizable as your voice, walk, or facial features.


As it turns out, the subtle ways humans breathe reflect a variety of influences. Your lung capacity, posture, muscle tone, emotional state, health conditions, and daily habits such as smoking or exercise all shape the unique way you breathe. Those small differences work together to create a remarkably consistent personal breathing pattern.

Although those patterns fluctuate with activity, mood, or stress, the unique recovery rhythms and variability in each person’s breath weave together into a biometric signature that may one day rival fingerprints or facial recognition as a secure method of identification.

Japan’s "ama" can spend up to two minutes underwater on a single breath.

Ama (“women of the sea”) are freedivers in Japan who have practiced breath-hold diving for centuries, employing their abnormal lung capacities to harvest shellfish and seaweed without any breathing gear. This practice likely began in coastal hunter-gatherer communities wherein women gathered seafood near the shore. While male divers also existed, women’s higher percentage of body fat made them better suited to withstand the cold waters.

Over time, the role became the exclusive domain of women, often passed down from mother to daughter, with some divers starting as early as age 12 and continuing into their 60s or 70s. Their incredible lung control and calm mindset enable them to dive deep in cold waters, preserving a 5,000-year tradition that continues today.

Humphrey Bogart never says, “Play it again, Sam,” in “Casablanca.”

  Despite being one of the film’s most oft-quoted lines, the words “Play it again, Sam” are never said in  Casablanca . It’s been called “ probably the most misquoted line in cinema history ,” not least because it’s usually attributed to the wrong character. The 1942 film’s protagonist, conflicted Morocco nightclub owner Rick Blaine (Humphrey Bogart), is often imagined as the one saying the line, even though the closest equivalent — “Play it, Sam” — is actually said by Rick’s endangered ex, Ilsa Lund (Ingrid Bergman). (Rick does later instruct Sam, the piano player in question, to “play it,” however.) For all that,  Casablanca,  a noir classic set in WWII, still has many other memorable lines, including six on the American Film Institute’s  100 Years… 100 Movie Quotes  list, the most of any film. (That includes “Here’s looking at you, kid” and “I think this is the beginning of a beautiful friendship.”) Of course,  Casablanca  is far from the only ...

The Stories Behind 7 Beloved Good Luck Symbols

  Share to Facebook Share to Twitter Share to Email Are you feeling lucky? It’s possible you just came across a patch of four-leaf clovers, or walked underneath a horseshoe. Maybe you were just given some lucky bamboo. But why are these things considered lucky? And what’s the story of the “lucky cat” next to your favorite Asian restaurant’s cash register? The number seven is supposedly lucky, too — so we’ve rounded up seven good luck charms and the stories behind them. Credit:  New Africa / Shutterstock Four-Leaf Clovers Part of the reason four-leaf clovers are lucky is pretty simple: They’re  exceedingly rare . Clovers have four copies of each chromosome in every cell, and all four copies need to carry the gene for the fourth leaf in order for the plant to produce one. Environmental factors can affect the expression of the trait, too. One survey in 2017 found that around 1 in 5,000 clovers have four leaves, although they tend to be found in patches. How clovers and ...
