New Delhi -- Legendary superstar Amitabh Bachchan, who is recuperating at home after undergoing abdominal surgery last month, stepped out of his residence for the first time on Sunday to greet fans. The 69-year-old actor thanked well wishers, who had gathered outside his house to get a glimpse of the actor. "God bless the well wishers. God bless them for their permanence in my life. God bless their consistency, their love and enthusiasm. I am indebted for life. It is a debt I shall never be able to repay; the one burden that shall remain with me unattended. One burden that shall make me happy," Bachchan posted on his blog.
