Online reports, the Wall Street Journal reported on Wednesday that Warren Buffett revealed he decided to step down after finally feeling the pressure of age. Reported that Buffett could not pinpoint the exact moment when he decided to hand over control of Berkshire Hathaway to Greg Abel. But in recent years, Buffett has noticed the energetic energy the designated successor shows when he works every day, and the slowdown in his own work pace. The two men's working conditions are operating at different speeds-and the gap is growing. "There is no magic moment," Buffett, 94, told the Wall Street Journal."How do you know the exact date when you're getting older?" "For some strange reason, I didn't really get older until I was about 90," he said by phone from his Omaha office."But when you start to age, the process becomes-irreversible." (Jin Shi)
