Barack Obama has revealed that he hasn't smoked in years, and all the credit goes to his wife, first lady Michelle Obama.
According to a CNN report, the US President was heard asking a U.N. official, Maina Kiai, during a private conversation, about his smoking habit, the Huffington Post reported.
When the official asked Obama about his own cigarette use, Obama said he hadn't had a cigarette in six years, because he is scared of his wife.
Michelle has actively promoted healthy habits in kids and adults.
