A Japanese YouTuber has gone viral for having what he claims to be the world’s longest chin.
The social media sensation, who goes by Jonouchi, claims that he was born with an unremarkable chin but at when he was about five his mandible started growing—and didn’t stop until it was abnormally long.
Whilst doctors are not entirely sure what has caused his chin to become so long and pointed, Jonouchi believes it’s because he drank so much milk as a child.
He told his 350,000 YouTube followers that he drank milk every day as a child in the hopes of growing taller, but only his chin got longer.
Milk is naturally high in calcium, and it is the most abundant mineral in the body.
It plays a part in building bones and keeping teeth healthy, while also supporting the muscles, nerves and heart.
Calcium plays an essential role in the body, but too much can lead to serious health problems.
High calcium levels in the blood—known as hypercalcemia—can actually lead to poor bone health.
Jonouchi claims to have the world’s longest chin, a feature which has baffled doctors
Doctors are not convinced milk triggered the growth of ‘the world’s longest chin’, with most saying Jonouchi’s unusual feature is likely to be genetic.
He had sought help from a number of health professionals, from doctors to dentists, and had x-rays to try and find out what powered its growth.
However, his long chin and defined jawline continues to mystify doctors who say they have never seen anything like it.
Jonouchi says that he is the only one in his family with the defining feature so is not convinced that it is hereditary.
In one of his videos he speculated that it may be the result of his unusual tongue habits.
‘There are a couple of reasons why a chin might stick out like this,’ he said.
‘The first is congenital, meaning someone was born with it or its naturally prominent.’
The second more likely reason he gave for his extraordinarily long chin was that he acquired it over time.
He said: ‘If you leave your tongue sitting low all the time, that force pushes on your lower jaw, and over time it gradually causes your chin to extend outward.
‘So your jaw literally gets longer. For me that’s exactly what happened—it kept stretching out over time,’ he added.
Whilst the now-infamous YouTuber used to get bullied for his looks, and has even been rejected by romantic interests, he has now turned his chin into his personal brand, and amassed an impressive 500,000 followers across various platforms.
Whilst this may sound like a one-of-a-kind phenomenon, tongue placement has taken the social media world by storm in recent months.
In a trend known as mewing, proponents of the technique say that placing the tongue against the roof of the mouth whilst setting the teeth together can help define the jawline and improve facial symmetry.
Popularised by a now disgraced orthodontist Mike Mew, the technique has even been credited with alleviating jaw pain and stopping people from snoring.
The former doctor has now been struck-off following claims that he tested out invasive and harmful treatment on to six-year-old children to realign their teeth and lift their jaws.
