How to Lower Cholesterol in 8 Simple Steps
My husband was in Vietnam in 1970 he died 5 1/2 yrs. ago with artery disease. He had several arota aneurysm surgery with also a valve replacement. His very last surgery was succesful then he caught every infection the hospital had started bleeding internally and couldnt be opened back up due to the infections. I always wondered where all of this could have came from. Sorry to hear about your husband.
