A 15-year-old Australian boy is aiming to become the youngest person to scale Mount Everest.
Mount Everest is notoriously treacherous
Christopher Harris, who has already conquered four of the world's seven highest peaks, started rock climbing aged five.
"I'm a bit nervous - but I'm really excited and looking forward to it, I can't wait," he was quoted as saying by the Sydney Morning Herald.
More than 186 people have died on the world's highest mountain since 1922.
"Reaching the top, just hanging off ice cliffs, turning your head and looking at the view will be amazing," said the teenager from Emu Plains, 55km (35 miles) from Sydney on the edge of the Blue Mountains.
"I'm a little bit scared but I'm 100% ready," he told The Age.
His team will include his father, Richard, and top Australian mountaineer Lincoln Hall.
The person who currently holds the record as the youngest person to climb Everest is female sherpa Ming Kipa, also 15 at the time, but Christopher Harris will be three months younger than she was when he attempts the ascent in May.
Nepal has banned anyone under the age of 16 from climbing the mountain, but Christopher will attempt to scale it from the north side, which is the Tibetan route.
