British royal Prince Harry took his coolness to a whole new level after spending a night in a giant freezer in Nuneaton, UK.<br/> <br />The 29-year-old prince woke up to temperatures around minus 35 degrees Celsius or minus 31 degrees Fahrenheit and winds up to 45 miles, or 72 kilometers per hour.<br/> <br />He did this in preparation of a 15-day trek to the South Pole in November, to benefit the charity "Walking with the Wounded."<br/> <br />Prince Harry is the patron of the non-profit that benefits wounded veterans and all of his four teammates have amputated limbs after serving in Afghanistan.<br/> <br />While a trek in the bitter cold seems daunting to many it's actually nothing new for Harry.<br/> <br />Two years ago he took part in a similar trek to the North Pole, but he had to pull out early to attend his brother, Prince William's wedding to Kate Middleton.
