Since taking office in 2009, President Obama has aced three physicals. He regularly exercises, especially playing basketball, and has a personal chef—not to mention wife—who ensure he eats healthy. But he has one (potential) vice that keeps coming back up: smoking. A photo posted on Instagram by a spokesman for Italian Prime Minister Matteo Renzi buzzed around the Internet this week because it appeared to show President Obama on an outdoor balcony at the G7 summit holding what might be a pack of cigarettes.
