On the same day he was released from a hospital after undergoing a heart procedure, former President Bill Clinton told reporters he has no plans to slow down. "I have to keep working -- that's what my life is for," he said outside his home in Chappaqua, New York, on Friday. "You know I was given a good mind, a strong body, a wonderful life and it would be wrong for me not to work." "I even did a couple of miles [walking] on the treadmill today," he was quoted as saying by CNN. On Thursday, Clinton, 63, underwent a procedure at New York-Presbyterian Hospital's Columbia campus to implant two stents in a clogged coronary artery. Clinton has "no evidence of heart attack or damage to his heart," and his prognosis is excellent after undergoing the procedure, according to Dr. Allan Schwartz, the hospital's chief of cardiology Schwartz said the procedure was "part of the natural history" of Clinton's treatment after his 2004 quadruple bypass surgery and "not a result of either his lifestyle or diet, both of which have been excellent." Clinton called the procedure "kind of a repair job" and said he's "actually doing very well."
