JUMPING through a hoop of knives blindfolded or somersaulting over a car in the middle of the street would fill most people with deadly fear.
But celebrity stuntman Marcelo de Ramos 'The Daredevil' says it is these kind of moves that saved his life.
The Brazilian, who has lived in Sheffield for the last 12 years, grew up in the rough side of Rio - and admits half the friends he left behind are now dead after getting in with the wrong crowd and the wrong lifestyle.
Instead Marcelo is wowing audiences with talents - and sheer bravery - on prime-time programmes including X Factor and Britain's Got Talent.
His 13-year-old son Jordan is also coming on leaps and bounds - and has already won the gold medal in the British Tumbling Championships three times at such a young age.

It all started when Marcelo was aged 11 and his mother Ivone gave him permission to go travelling around Brazil with the circus.
He learnt all the skills including juggling, stilt walking and acrobatics, and by the age of 17 was a performer ready for the Brazilian National Circus.
From there came offers of work on children's TV shows, which in turn led to roles in Brazilian movies, and by 1990 aged 20 he had received recognition as a professional stuntman.
After a spell performing with a show in Germany - where he met his dancer wife Anita - they came to England, and settled in Sheffield where they both worked as entertainers at Meadowhall.They lived in Wincobank, set up an acrobatics school in Rotherham, and had another son Samuel, now aged four.
But it was last year that things really 'leapt' into action for the Ramos family, who now live in Chapeltown.
Marcelo, 37, performed as a juggler in the backing routine for brother-sister duo Same Difference in the X Factor semi-final, and staged a jaw-dropping dislocation of his neck to impress judges on the Britain's Got Talent competition.
He even brought his stunts to the streets of Sheffield - when he jumped over his 61-year-old mother in Barker's Pool. But he said the highlight had to be performing for Donny Osmond on the BBC's 'Identity' programme - when he jumped through a hoop of knives and was described by the singer as "unbelievable".
Marcelo said: "He even started helping me - holding up the hoop for me and clapping me along.
"It should be the other way around - it's unbelievable that he was saying I was unbelievable!"
For Jordan, who did his first backflip off the sofa when he was just four-years-old, the year brought his third victory as British Tumbling Champion, and was the first time he had competed in the World Championships where he landed sixth place.
Half a million people also tuned into You Tube in just a few days to watch him in action, which in turn led to appearances on prime time breakfast television sharing his skills with the nation.
But they both admit that 2008 looks set to be bigger and better still.
Return to news section. They're currently working on an acrobatic stunt show together to be aired on television later this year, while Jordan has recently been approached by Blue Peter, and Marcelo is in talks about going stateside with his own stunt show.
