Russian President Vladimir Putin says he probably won't run Moscow forever, though he could run for another six-year term in 2018."This is not good and detrimental for the country and I do not need it as well," Putin said when asked if he wanted to be president for life, according to Russian state media.The 62-year-old Putin has been president since 2000, excepting a four-year stint, from 2008 to 2012, when he served as prime minister.
