For instance, director of the Sleep Assessment and Advisory Service Chris Idzikowski explained that people who opt for the fetal position "may appear tough but are actually sensitive souls right to their core."

There are a lot of things happening in our bodies that we have no control over. For instance, most of us can't control the size of our pupils unless we do something like alter the amount of light that is directed into our eyes. However, in a study published in the International Journal of Psychophysiology in 2021, researchers observed a man who can apparently change the size of his pupil on command. Currently, he is the only individual known to be able to do this—although you could give it a try if you want!

You remember from grade school that all humans are made up mostly from water, but never more so than right after we're born. Newborn babies are 78 percent water, according to NASA, while adults drop down to around 55 percent to 60 percent.

It's likely horses you picture bounding across a landscape, not something scaly and low to the ground. However, a study published in Nature in 2019 noted that crocodiles have the "full range of quadrupedal footfall patterns used by mammals," meaning that they have the ability to gallop like a horse—and occasionally do! Of course, they don't look quite as graceful, but they can reach speeds of up to 11mph.

The key ceremony is a (perhaps now not-so-very) secretive meeting of some powerful people who have a staggering amount of control over the internet. As reported by The Guardian, these seven keyholders are handpicked security experts who meet quarterly and whose individual digital keys "create a master key, which in turn controls one of the central security measures at the core of the web." The experts have exclusive access to the domain name system (DNS), which is basically the directory of everything online, "as part of a new global effort to make the whole domain name system secure and the internet safer." Every time they meet, they flush out fake and dangerous web addresses.

The Sun reported on the astrological analysis done by UK Domain on the most recent Forbes list of billionaires. As it happens, Libra claimed the most—an impressive 27 billionaires.

In 2011, a hiring manager for a Chinese language training company included in a job listing that candidates who were Virgos or Scorpios need not apply. Obviously, there was backlash to the discriminatory policy, but the hiring manager doubled down to a local newspaper, claiming that she was counting those signs out because they have a tendency to be "feisty and critical."

Blood type personality, or ketsueki-gata, is a Japanese belief that it's one's blood type that may determine aspects of their personality. According to Very Well Health, the pseudoscience can be traced back to 1930 when a professor named Tokeji Furukawa suggested the possibility that there could be a correlation between blood types and certain traits. People with A blood are thought to be creative and stubborn, for example, while those with O are confident and self-centered.

At least among women, that is. A 2013 survey of 10,000 U.K. women reported by Hello! found that Leos were twice as likely to go to the gym compared to any other sign.
