In her new autobiography, “Miles To Go”, the Hannah Montana star reveals that she has a heart condition called “Tachycardia” which means her resting heart rate pumps faster than normal. Even though the condition is not life threatening, Miley Cyrus admits:

“The type of tachycardia I have isn’t dangerous. It won’t hurt me, but it does bother me. There is never a time onstage when I’m not thinking about my heart.”

Do you think a 16-year-old has had enough of a life to fill a whole book? Seriously, what is she gonna start with? Her experience with potty training?
