Here are a couple of additions to the Believe-It-Or-Not series. Did you know that 11.7 per cent of the worlds GDP (thats worth $3.5 trillion) comes from the travel and tourism business, and that this industry provides 200 million jobs to people around the world? Of this, $400 billion-thats more than Indias GDP-comes from the 75 million business trips that corporate executives around the world make every year. And if one goes by a recent American Express study on corporate travel, this figure is growing at four per cent a year.
