Since 1969, America has designated February as “Heart Month” — a distinction that’s personal for me. Eleven years ago, shortly after I was sworn in to Congress, I was taken to the hospital after fainting during a workout. The good doctors at The George Washington University Hospital diagnosed me with bradycardia (a slow heartbeat) and outfitted me with a dual-chamber pacemaker. I flew home the next day and have been healthy ever since. Others are not as lucky.
