People generally place the natural world in high esteem. Property values are high near parks. “Getting back to nature” is considered a good thing. Even our screensavers and desktop backgrounds show vistas of rolling hills, sunshine or the aurora borealis. But we usually gloss over the fact that while Mother Nature is normally a very sweet lady, she can sometimes go off the deep and blow your mind... or ruin your shit, as evidenced by this nonet of natural madness. While not as mysterious as some of the other entries you’ll see on this list, fire tornadoes are among the most badass examples of extreme weather... proof that Mother Nature remembers her younger days and still likes to get crazy from time to time.
Thunder and lightning storms are a hallmark of summer in many areas of the world, but the conditions that produce them are rarely found in winter months. The exact cause of the shimmering lights that sometimes appear before some heavy seismic activities is currently unknown.

Proprioception Wiggle where you're at Even with our eyes closed, we have a sense of body position - where our arms and legs are, for example, and that we are moving them.
Muscles, tendons, joints and the inner ear contain proprioceptors, also known as stretch receptors, which relay positional information to our brains. Our brains then analyze this information and provide us with a sense of body orientation and movement.

Late on a Saturday night in September, a 14-year old boy named Jamey Rodemeyer, who had been the target of bullying from fellow students at Williamsville North High School in Buffalo New York, took his life. Just hours before he killed himself, Jamey left the last of his numerous messages online talking about the pain he had been dealing with for a long time. Jamey’s suicide was a terrible, extreme reaction to being bullied, and tragically, his was not an unusual case.
According to some reports there were as many as 10 teen suicides in the month of September this year, in the United States, that were linked to bullying. Violent reactions by teens to being bullied are not new. It was boys that were bullied and ostracized that committed the high school shootings that plagued the US in the 1990’s. From those mass slaughters to the present day rash of suicides, bullying is taking a violent toll on the youth of America. Bullying-like behaviors are not restricted to female primates.
