THE HUMAN HEART RENEWS


inspiration


ITSELF Researchers at Karolin- ska Institute, a leading medical university in Sweden, have demonstrated that contrary to con- ventional theory, heart cells are able to regener- ate themselves. Examining the heart tissue of 50 people over the course of four years, the researchers found that new heart cells appeared to replace older ones at a rate of approximately 1 percent per year in people in their 20s, falling to 0.5 percent per year by age 75. Scientists now hope to find ways to stimulate this natural regeneration of heart cells as a way to avoid heart transplants and help people recover from heart attacks.

gist. “When you are quiet, the silence blows against your mind and etches away everything soft and unimportant. What is left is what is real: pure aware- ness and the very hardest questions.” It’s not easy to find silence, which is


In recent years, multiple studies have touted the benefits of following a diet rich in antioxidant vitamins such as C and E. Now, new findings show that while antioxidant-rich foods are fine when eaten in large quantities, taking too many antioxidants in supplement form can put our health at risk. Researchers at Cedars-Sinai Heart Institute report that many people take way too many vitamins, believing that if a little is good, a lot must be bet- ter—but that is not the case. “If you are taking 10 or 100 times the amount in a daily multivitamin, you may be predis- posing your cells to developing cancer,” warns institute Director Dr. Eduardo Marbán, who led the study.


facing extinction in the modern world. If a quiet place is one where you can listen for 15 minutes in daylight hours without hearing a human-created sound, there are no quiet places left in Europe. There are none east of the Mississippi River and perhaps 12 in the American West, includ- ing one square inch in the Hoh Rain Forest at Olympic National Park, now officially recognized as the quietest place in the United States (OneSquareInch. org). In defending this exemplary spot of silence, Hempton is effectively protecting the soundscape of about 1,000 square miles of surrounding land. Hempton defines silence


not as noiselessness, but “the complete absence of all au- dible mechanical vibrations, leaving only the sounds of nature at her most natural. Silence is the presence of everything, undisturbed.” Silence, he would concur, is not the absence of sound, but a way of liv- ing—an intention to make of one’s own ears, one’s own body, a sounding board that resonates with the vibrations of the world. Silence creates an opening, an absence of self, which allows the larger world to enter into our awareness. It


brings us into contact with what is be- yond us, its beauty and mystery. Hempton encourages us all to join in the self-discovery of nature. He’s found, “All we have to do is listen.” Sounds, more than sight, connect us, he observes. In learning to listen to nature’s nuances, we also learn how to listen to one another. His favorite time of day for listening to nature is 30 minutes before sunrise. When the atmosphere is still, “It is not unusual to hear many square miles at once.” Astonishment and gratitude illumi-

nate our being when light breezes play across leaves and set them in motion, chirruping night insects wind down and the birds’ dawn chorus begins. When our moving a stone in a creek bed alters the water music, it is we who are moved. No one knows why natural sounds speak so directly to the human spirit, but we all acknowledge, in silent thanksgiving, that they do.
