Microsoft Corp chairman and the worldÆs richest man Bill Gates is starting to think about retiring after heart-to-heart talks with financier Warren Buffet, the second wealthiest person in the US. According to a report in the Times, he is giving a lot of thought to the person he will hand over to but reckons it will be five years before he has to do something about it. Gates and 68 year-old Buffett have become good pals and discuss what to do with their fortunes over endless games of bridge. Given that he is just 42, the fact that Gates is considering retirement suggests that he is getting a little jaded, worn down possibly by increasing brushes with regulatory authorities. Those who know him suggest that Gates will never be able to walk away from Microsoft and forget entirely about the company he founded.
