Most climbers take several months to scale Mount Everest, gradually heading up and down to acclimatize to the lack of oxygen. British politician Alistair Carns says he is aiming to do it in just four days with the help of a controversial gas.
Next month, the 45-year-old Minister for Veterans and People will fly to Nepal with three ex-Special Forces pals to climb the world's tallest mountain in a matter of days. They hope to arrive on a Monday, summit by Thursday, and be back in London for Sunday.
