Sample this from Bloomberg News: "Carlos Slim, the telecommunications tycoon who controls Mexico's America Movil SAB, is the richest person on Earth, according to the Bloomberg Billionaires Index, a daily ranking of the world’s 20 wealthiest individuals. The 72-year-old’s net worth was $68.5 billion as at March 2, as US moguls Bill Gates and Warren Buffett placed second and third on the list. Brazil’s Eike Batista, 55, who ranks 10th, still covets the top spot after vowing a year ago that he’d become the world’s wealthiest man by 2015." Now that’s is ambition, or does Mr Batista know something we don’t? How about an autograph Eike?
