Victor,
All good advice for living longer and healthier. Eating healthy, regular exercise, keep the weight down, etc.. all go a long way in preventing coronary artery disease. Unfortunately, most folks cannot, and will not follow those rules as strict as they should. Consequently, those arteries begin plugging up with fatty deposits that eventually turn into plaque.
Other factors, however, have recently come to light, some of which we have little or no control over. Genetics, of course, plays a major role. Additionally, some light has been shed on various inflammatory diseases that are believed to have a direct effect on the coronary arteries, causing plaque to rapidly form.
Keep in mind that most of us (synthzoners) are beyond the age where significant changes in life style will produce dramatic results and extend our lives. (Diki excluded!) If you're 60 years old or older and you have recently undergone bypass surgery or stinting, it's unlikely that you'll dramatically change your lifestyle and live 30 more years.
Cheers,
Gary
