Jim Rogers, the market sage, has warned the global economy is just two years away from another recession, but remains ill-prepared to cope with the after-effects. Mr Rogers, the respected currency trader and hedge fund pioneer, cautioned that when the downturn takes hold "the world is going to be in worse shape because the world has shot all its bullets." Speaking in an interview with business television channel CNBC, the septuagenarian investor said that "since the beginning of time" there has been a recession every four-to-six years, and that's mean another one is due around 2012.
