Lengthening your limbs with the help of surgeons is quite the controversial topic in the health sphere.
Hundreds of people across the globe fork out ridiculous amounts of money to grow a few inches in height, despite the procedure being invasive, costly and coming with a lot of risks.
However, it's given this nine-year-old boy a new lease of life - and he has gleefully told how now 'towers over' his school pals and thrashes them at basketball.
Alfie Phillips became the first patient in the UK to have leg-lengthening surgery in March last year and medics can't believe how 'remarkably quick' he recovered.

The youngster, from Northampton, has a rare condition called fibular hemimelia. This means that he was born with a short or missing fibula bone.
In Alfie's case, it resulted in his right leg not developing properly, so it was around 4cm shorter than his left.
Although his mum, NHS midwife Laura Ducker, said he 'never really had significant problems' because of this discrepancy, she was told it could cause trouble later down the line.
Doctors warned that Alfie could face issues with his hips and joints in the future, while predicting that the difference in the length of his legs would have increased to 6cm by the time he turned 16.
The young lad explained his classmates were often left 'confused' about why he wasn't as tall as them, while his peers also pointed out that he 'ran a bit different and couldn't skip.
Alfie told PA: "I was around five and six when it started to get a bit annoying. If they ever wanted a conversation, other than my friends, it was always going to be about my condition."
Initially, doctors said his only option was to have an external frame fixed to his bone from the outside of his limb, which doctors say can be 'difficult to live with'.
External fixators can cause pain, infections at the pin sites and complications like knee stiffness and scarring.
But in 2024, Alfie was given another lifeline after being referred to Alder Hey Children’s Hospital in Liverpool by his GP.
Specialists explained they could lengthen his legs with a new surgical method that was developed in the US. Previously, lengthening procedures couldn't be performed on kids due to the risk of causing damage.
The operation that Alfie had involved placing a lengthening nail, known as a motorised telescopic nail, on the surface of his femur, which is the long bone in the thigh.
The bone is surgically cut, with a rod placed down the middle to keep it straight. To make the limb longer, a magnetic device was placed on Alfie’s leg three times a day for a month.
This process helped the nail slowly pull the two bone ends apart - by around 1mm each day - while the body naturally filled the gap with new bone tissue.
The nine-year-old spent less than a week in hospital. Alfie then returned for weekly physiotherapy sessions and reviews throughout the lengthening process. Over around six weeks, his leg crew 3cm in length.
About four months after undergoing the op, the nail was removed from Alfie's leg and his mum Laura, 34, said her son 'healed really well', adding: "He coped magnificently.
"He’s running around as normal, if you were to look him you would never know that there had ever been anything happen. He is just incredible."
Nick Peterson, a consultant orthopaedic surgeon at Alder Hey, also praised Alfie's recovery as 'remarkable', while explaining that this case 'paves the way for this technique to replace that old fashioned way of doing things'.
He said the difference in the length of each of Alfie's legs would not have been 'something that you could manage a normal life with', hence why surgical intervention was necessary.
The boy may need further lengthening treatment on his shin bone in the future, but for now, he's enjoying his new giant status.
"The main thing I enjoy is obviously being first in the UK to have the operation, and mainly being taller than my friends, which is nice," Alfie added. "I can just tower over them now...I like doing basketball a lot."
Three other children with fibular hemimelia have since undergone the same surgery as Alfie at Alder Hey and Dr Peterson said his colleagues around the country have shown a 'huge amount of interest' in the technique.
