Guys, I've been an EMT for 8 years, and have an ex-wife who was a physician. Together we have had several calls with young people (usually under 30) with heart attack symptoms. Family history has TONS to do with it. People that eat healthy having high cholesterol readings is not uncommon. It's also in the genes. I personally frequent the Hardee's, Pizza Huts, steak sub joints....my readings are very low, but the family dosen't have a history either.
