Joe Biden is “healthy, vigorous” and “fit to successfully execute the duties of the Presidency,” according to a doctor’s report released Tuesday by the 77-year-old former vice president. Dr. Kevin O’Connor, who has been Biden’s primary care physician since 2009, writes in a three-page note that the Democratic presidential candidate is in overall good shape — he’s trim, exercises and keeps his cholesterol at healthy levels with the use of a statin medication. Since 2003, Biden has had episodes of atrial fibrillation, a type of irregular heartbeat that’s potentially serious but treatable.
