Very surprised this was not mentioned at all on his VT or by the press before, but this is on this site.

Born in Blackburn England with a benign tumour on the left side of his head, he was raised in the village of Mellor near Blackburn. At the age of 3, he suffered from a rare disease known as Kawasaki’s Syndrome, which can be fatal. This caused total deafness in his left ear, which led to numerous hospital admissions and outpatient appointments.
The removal of the tumour left Cristian MJC with a large scar and combined with his deafness created problems with classmates and teachers who didn’t understand his deafness properly. This lead to him attending 4 primary schools in total.
After witnessing the death of both his maternal grandparents, and the effects ‘Meningitis’ had on his father, he became sure he wanted to study medicine and become a doctor. What fascinated him, was possessing the ability to alleviate the pain suffered by many, through his own personal skills.
People online were laughing at his breakdown and a few posters said (on DS) "Oh yeah, I'm sure you had a tough life". Never judge anyone. You don't know what someone has gone through. You can't assume someone has had an easy life based on how they act, they look etc...
