"After three months, we repeated the biopsy and looked at changes in normal tissue within the prostate. We found that many disease-promoting genes (including those associated with cancer, heart disease, and inflammation) were down-regulated or "turned off," whereas protective, disease-preventing genes were up-regulated or "turned on." For example, a set of cancer-promoting oncogenes called RAS was down-regulated in these men. The Selectin E gene (which promotes inflammation and is elevated in breast cancer) was down-regulated. Another gene that suppresses tumor formation called SFRP was up-regulated, thereby reducing the risk of cancer. These genes are the target of many new drugs that are being developed. Clearly, changing lifestyle is less expensive, and the only side-effects are good ones. "
When most of us think about environmentally friendly places, we imagine rural landscapes and bucolic open spaces. We picture a terrain untouched by concrete. Cities, in contrast, seem like ecological nightmares. They are densities of pollution, artificial environments where nature consists of cockroaches, pigeons and florist shops. But, according to Bettencourt and West, the conventional wisdom is exactly backwards. Cities are bastions of environmentalism. People who live in densely populated places lead environmentally friendly lives. They consume fewer resources per person and take up less space. (On average, city dwellers use about half as much electricity as people living outside the city limits.) The typical Manhattanite generates 30 percent less CO2 than the typical American.
