World Heart Day is held each September 29 under the auspices of he World Heart Federation, a non governmental Swiss agency which promotes cardiovascular and cerebrovascular health.
They advocate small changes making powerful differences in the risk factors and disease processes themselves.
Their site is full of infographics and warning signs for heart attack and stroke and inasmuch as these two diseases remain the cause of death for most people it's a good idea to place your best foot forward and get attuned to the facts and remain "in the know".
Heart Healthy is more than just a buzz word. It's an attainable goal and way of life. So if you're so inclined mark World Heart Day as one of those meaningful observances people can have with one another.
