POPSAnti-intellectual Presidency book review
One might also question whether public engagement with policy issues was, in truth, significantly higher when presidential speeches were pitched higher. How many ordinary Americans could wax eloquent about the pros and cons of the gold standard in the 1890s, despite the fact that orators of the level of William Jennings Bryan were making the rounds? The electorate that listened to Wilson went on to elect Harding, partly because he was handsome and partly because he made speeches high on pathos. Moreover, his “return to normalcy” mantra used a word many considered not even to exist. Nevertheless, amid the impressionistic plaints so common against the dumbing down of American culture, The Anti-Intellectual Presidency is a useful empirical demonstration of one facet of a larger cultural transformation. In our come- as-you-are America, Dick Cheney’s response to an interviewer’s observation about widespread public opposition to the war in Iraq with “So?” is business as usual. We might di

POPSDo we get wiser with age? "Is age a prerequisite for wisdom, though? We all know a few elderly people who lack wisdom, while we may know few young people that have wisdom in spades. People certainly aren't always at peak brainpower in old age; after all, when wrinkles begin appearing on the face, it usually means that wrinkles have started disappearing on the brain. The brain shrinks slightly with age, and aging leads to a normal decline in cognitive function that may eventually bloom into dementias such as Alzheimer's disease".

POPSPotential Alzheimer's, Parkinson's Cure Found In Century-old Drug Also impressed is one of Dr. Atamna's co-authors, Bruce Ames, PhD, a senior scientist at Children's and world-renowned expert in nutrition and aging. "What we potentially have is a wonder drug." said Dr. Ames. "To find that such a common and inexpensive drug can be used to increase and prolong the quality of life by treating such serious diseases is truly exciting." Dr. Atamna's research is the first to show that low concentrations of the drug have the ability to slow cellular aging in cultured cells in the laboratory and in live mice. He believes methylene blue has the potential to become another commonplace low-cost treatment like aspirin, prescribed as a blood thinner for people with heart disorders.

POPSHow your inner athlete makes you smarter
also from article: Even when we are sitting or lying down, our bodies send our brains regular updates about how our limbs are positioned. When we, say, stand and begin walking, these electric messages need to be sent more often. (Knee is bent, straight, bent, straight ...) Move fast enough and the electrical activity doesn't have time to dissipate between each message. It begins building up in the brain and eventually triggers a release of chemicals called growth factors. Growth factors are like manna for neurons. "They make neurons stronger, healthier and improve their ability to learn," Cotman said. In the presence of growth factors, new neurons are born and old ones sprout, grow and form better connections with each other. Blood vessels blossom along side the neurons, giving them quick access to glucose and other nutrients. All this, in turn, improves our ability to think, learn and remember. As Cotman said, exercise "builds the pipes" for improved cognition.
