Mezrich: ...This is the cool is the cool part of the story. Yeah, the tundra has a permafrost that’s like a ticking time bomb that if it went off would be worse than if we burned all the forests on Earth three times, and this permafrost is always getting close to melting ( Editor’s Note: Mezrich is talking about the potential for a catastrophic methane release from melting Arctic permafrost ) . These scientists, the Zimoffs, have been running this experiment since the 80s where they rope off a part of the tundra and repopulate it with Pleistocene type herbivores. They’ve put bison in, reindeer reindeer, horses, a WWII-era tank that they drive to mimic a mammoth, knocking down trees. And they’ve discovered they can lower the temperature by as much as fifteen degrees, which is an incredible thought (Editor’s Note: This is a speculative idea that Mezrich describes in more detail in the book, in which Pleistocene herbivores might help transition forests and shrub lands into grasslands, which absorb less heat.) The idea is to repopulate the area with mammoths. Church’s goal is 80,000 mammoths, and [he hopes that] you could lower the temperature of the permafrost for generations.
About 84% of adults will experience some sort of back pain in their lives.  Upper back pain, although less frequent than lower back issues, is a problem for many today. Because the thoracic spine in the upper and middle back region is not as mobile as the lower back and neck, injuries are not as common. However, upper back pain can develop due to poor posture and chronic muscle tension. If you suffer from upper back pain, then exercise,  good posture, and lifestyle changes may minimize bouts of discomfort, or even eliminate them completely.
A distinction should be made between electromagnetic sensitivity, and symptoms an individual labels as such. Researchers have failed in proving that those claiming sensitivity to electromagnetism can accurately determine the presence of a strong electromagnetic field. Nevertheless, the perceived symptoms are real for the patient, and should be honored as such, or until it can be demonstrated that they are psychosomatic or have some other physical source. Many people who meditate, for example, perceive energy movements in their body and learn to work with these. But a second distinction must be made between those who successfully work with unusual psychological states and these who find them debilitating. For the later, either drugs or meditative practice may or may not be helpful. Overcoming, defusing, or sublimating debilitating mental states is never easy.
