Nearly 1 in 3 adults has high cholesterol. That should certainly grab our attention. To get a clearer understanding we have cardiologist, Dr. Rosemary Peterson who works with this on a daily basis, to explain why high cholesterol is often called 'the silent heart attack'. And we also meet a man, Joe Farrington, who less than 2 years ago experienced 'the silent heart attack'. Doctors informed him that he should not be alive when he finally had his appointment. Joe's mission now is to live a healthy life and to educate others. www.heart.org
