The value of mental-training games may be speculative, as Dan Hurley writes in his article on the quest to make ourselves smarter, but there is another, easy-to-achieve, scientifically proven way to make yourself smarter. Go for a walk or a swim. For more than a decade, neuroscientists and physiologists have been gathering evidence of the beneficial relationship between exercise and brainpower. But the newest findings make it clear that this isn’t just a relationship; it is the relationship. Using sophisticated technologies to examine the workings of individual neurons — and the makeup of brain matter itself — scientists in just the past few months have discovered that exercise appears to build a brain that resists physical shrinkage and enhance cognitive flexibility. Exercise, the latest neuroscience suggests, does more to bolster thinking than thinking does.

“In the name of the best within you, do not sacrifice this world to those who are its worst. In the name of the values that keep you alive, do not let your vision of man be distorted by the ugly, the cowardly, the mindless in those who have never achieved his title.
Do not lose your knowledge that man’s proper estate is an upright posture, an intransigent mind and a step that travels unlimited roads. Do not let your fire go out, spark by irreplaceable spark, in the hopeless swamps of the approximate, the not-quite, the not-yet, the not-at-all. Do not let the hero in your soul perish, in lonely frustration for the life you deserved, but have never been able to reach.
Check your road and the nature of your battle. The world you desired can be won, it exists, it is real, it is possible, it is yours.”
~ Part Three / Chapter 7 This is John Galt Speaking
“The world you desired can be won, it exists, it is real, it is possible, it is yours. But to win it requires total dedication and a total break with the world of your past, with the doctrine that man is a sacrificial animal who exists for the pleasure of others. Fight for the value of your person. Fight for the virtue of your pride. Fight for the essence, which is man, for his sovereign rational mind. Fight with the radiant certainty and the absolute rectitude of knowing that yours is the morality of life and yours is the battle for any achievement, any value, any grandeur, any goodness, any joy that has ever existed on this earth.”
~ Ayn Rand’s last public speech (New Orleans Nov 1981)
Prevent computer vision syndrome with these seven simple eye-saving tips.
By Anna Soref
You’ve been sitting in front of your computer for two hours trying to ignore your stinging, dry eyes and get through your work. You can’t quit now….If only your eyes would stop burning.
Tired eyes and blurry vision are but two symptoms of what is now recognized as a broader problem called computer vision syndrome, or CVS. As computer use continues to rise, so do cases of CVS. A recent study showed that nearly 90 percent of employees who work with computers for more than three hours a day suffer from some form of eye trouble.
CVS has a host of causes, from improper lighting, screen glare, and an ill-adapted workspace, to poor posture and glasses or contact lenses with incorrect prescriptions, according to Kent M. Daum, O.D., Ph.D., of the School of Optometry of the University of Alabama, Birmingham. Infrequent blinking is another culprit. We blink to keep the eyes lubricated, explains Daum. When staring at a computer screen, we blink less, so the eyes become dry. And the more we concentrate, the less we blink, so casually surfing the Web may be easier on the eyes than focused work, he says. Also, deficiencies of vitamin A may cause severe eye dryness, so be sure to get enough.
While CVS has not yet been shown to damage vision, there is no need to put up with its uncomfortable symptoms. Proper workspace ergonomics, frequent breaks from the computer, and eye drops are easy solutions that work. (When choosing eye drops, stay away from those containing phenylephrine or other whitening agents that can worsen symptoms over time.)
Dimming the lights in the workspace can also reduce eye fatigue. “The eye adjusts to the relatively dim computer screen. If you have a brightly lit office, whenever you look away from the screen, your eyes have to adjust to that brighter light, which can lead to eye fatigue,” Daum explains.
In addition, Judith Lasater, Ph.D., author of Relax and Renew: Restful Yoga for Stressful Times (Rodmell, 1995), recommends adjusting the computer so that the eyes rest at the level just below the tips of the ears; this will put the head in a more relaxed, comfortable position. She also says to pull your shoulder blades down, “like tucking in a shirt,” for a long back and open chest.To release overall tension (which she feels contributes to eye distress), Lasater suggests a version of Savasana (Corpse Pose) tailored for the eyes. Lie down in Savasana with a stack of several books lying nearby on the floor by the top of your head. Place either a five-pound bag of rice or some sandbags halfway on the books and halfway on your forehead. Relax for 15 minutes. This will help the muscles in the head to loosen and relax.
I am at peace.
But if I could go back and talk to myself when I was 19 I would tell that girl not to use a solarium — that melanoma is not a small cancer that you just have cut out and you will be fine.
I may pass in another week or it could be two. If I really fight it out, I may even have six weeks left.
It’s scary, because I feel myself getting more tired, and each time I feel sleepy it worries me that I might not wake up.
So far I have lived 25 years. If I am lucky I will reach 26 because my birthday is on Saturday.
It is a short life, but I have lived it.
