Collin P. Quock M.D., F.A.H.A and Donna Lew from the American Heart Association visit GHA

Today we had the pleasure of meeting Dr. Quock and Donna Lew from the American Heart Association. Dr. Quock talked with our GHA classes about the American Heart Association, heart anatomy, heart diseases and risk factors. I particularly appreciated how Dr. Quock’s talk included information about his career and cultural sensitivity. The American Heart Association’s mission reminded me of our guest speaker on traditional Chinese medicine. It seems the emphasis is on maintaining health or health prevention.  Dr. Quock mentioned The Framingham study that found, “When the blood pressure is over 140/90 mmHg, the risk of death from cardiovascular disease is more than two times greater than a blood pressure of 120/80 or less.” Each year our senior class learns how to take a blood pressure. Each year we find at least three students with blood pressure well over 120/80. It is time to watch our health.

H.C.E.&I. Special Project Intro

This year we will put together a special project designed to promote healthy eating choices and a more active lifestyle for your peers. You will be supported by Kristia, our ESLI teacher, Donna Lew, from the American Heart Association, guest Nutritionists from UC Berkeley, guest lecturers, Andrew, our Student Support Coordinator, and of course Mr. O’Brien and myself. The end product, or the “campaign” will be determined later in the semester as we learn more about the importance of healthy eating and staying active. I was pleased to learn that all of you have already studied modern marketing techniques in your english class with Mr. O’Brien. I find myself catching up to your knowledge. I will need your help to make the concepts you learned in Mr. O’Brien’s class clear.
