In this world, there are a handful of people who have abilities which experts can't always fully explain.
Some people have been able to perform incredible feats which ought to have been beyond the ability of the human body to do.
In some cases, scientists have been able to identify the reasons why a person is able to do this, but in others they draw a blank on an explanation.
While many people do extraordinary things every day, there are those who can manage things that even the most determined of us couldn't.
Daniel Browning Smith

This 44-year-old American contortionist has been described as 'the most flexible person in history', and is also known as 'The Rubberboy'.
His incredible flexibility means he's got seven Guinness World Records under his belt, including the fastest time to enter a locked straitjacket, and has performed stunts such as passing his whole body through an unstrung tennis racket.
OK, so for this one scientists do know why Daniel has been able to do what he does, as he has a condition called hypermobile Ehlers–Danlos syndrome.
It gives him loose joints and stretchy skin that helped him with his incredible feats, though it did mean he had to quit performing as the condition can cause pain and means his limbs can easily dislocate.

This 37-year-old Russian woman claims she can see inside people's bodies, essentially having Superman's x-ray vision.
Experts are naturally sceptical of someone claiming they've got x-ray vision, but in tests she has correctly identified medical conditions in strangers.
Appearing on British TV show This Morning in 2004, she identified host Fern Britton had a sore ankle, and a year later when under scrutiny by the Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP), she got four out of seven people's medical diagnoses correct.
However, not all of her predictions are correct so maybe she's just a really good guesser.

If you thought insomnia was bad imagine not sleeping for decades, or at least that's what this 81-year-old Vietnamese farmer claims.
His family, friends and neighbours have claimed they've never seen him sleep, and the man himself claimed he hasn't really slept since 1962, instead getting his energy from 'green tea and rice wine'.
In a meeting with YouTuber Drew Binksy, the man said he did want to sleep but couldn't, so this 'superpower' really isn't all it's cracked up to be.
Yes, you could get so much more done, but a good night's sleep can't be underestimated.
For basically everyone else going even a couple of days without sleep would be placing us in serious medical danger, so don't try and see whether you have this supposed superpower.

The man with possibly the greatest memory in the world, Stephen is able to look at a landscape just once before being able to perfectly recreate it in his art.
An incredibly talented artist, the 49-year-old has been able to recreate the skylines and buildings of major cities around the world after just one look.
Top Gear fans might remember Stephen as the man who helped out Clarkson, Hammond and May with their art exhibition by drawing a car in front of New York City's Brooklyn Bridge, with him creating the scenery entirely from memory.
Wim Hof

The Iceman set Guinness World Records for the farthest swim beneath ice and the longest time in full body contact with ice.
He claims cold exposure and breathing exercises are the secret to his incredible feats and can improve your health, but scientists are divided on how true this is.
While remarkable, Hof's records have since been broken by others who have displayed similar capacity to withstand dreadfully cold temperatures.
However, this one comes with a massive 'don't try this at home' warning as there have been people who've died attempting to demonstrate they can take the cold temperatures.
