What Happens When Women Orgasim
resistant Brains
N or want to be ominous, but surely you have noticed or will notice if you do not you pass forty, how to Over time your legs and your brain have become more lazy. And, however much we care, our brains grow old and die, so that the foot still holding the gun must make a daily effort greater than when they were younger and were more outings.
However, you also you will have noticed that you are still capable of performing many complex tasks as well or even better than when you were a twentysomething. This is especially evident when it comes to tasks that probably learned long ago and have been held fast with an intensive and repetitive practice.
The reason for this resistance is partly due to that practice, areas of the brain responsible for a particular motor skills, perceptual cognitive or expand. To be more responsible area, every little brain damage associated with aging does not affect the whole area, so that the skills acquired will not be lost forever because neurons survive in this vast region that will handle the job.
Another justification has to do with that practice reduces the metabolic demand for oxygen by neuronal tissue responsible for the task. Thus, although age diminishes the oxygen supply to our brain, we can do the job with a lower supply, provided that it is a well established skill or competence. Ie, increases the efficiency of these neurons either trained, they require little fuel to do their job.
The combined effect of these phenomena effectively counteract the consequences of certain diseases or simply aging neuronal have for our cognitive performance. Despite the age, with few exceptions, do not lose our expertise at executing those tasks well established domain. However, that does not happen with new competencies and skills acquisition, which still requires good oxygenation and will be located in a small area of \u200b\u200bthe brain. In this case we must work harder and practice more than when we were younger until competition is well established, and increase the neurons involved, which also consume less O2.
is, like maintaining a good physical tone in old age requires more effort than in youth, learning new tasks require more practice to achieve a consolidation that will stand the test of time. Otherwise we will see how these newly learned skills evaporate generating an intense frustration, as we will have to start over.

Use Preparation H To Reduce Waistline
The PISA 2009 report on alleged
L for publication Data from the PISA report has re-generated an interesting debate about the quality of our education system, as in previous assessments, not standing out too well fall below the average for OECD countries. And as often happens after the publication of results, much of the analysis focuses on the comparison between countries, to infer from some of the characteristics of educational models of countries that are at the top of the ranking recipes to improve ours.
Many of these countries well placed, as South Korea and Finland, have educational systems that show some features that would not hurt to import, and that in no way suggest that what we need is a return to more traditional school. For example, increased psycho-pedagogical training of teachers, a lower requirement for the students repeat courses, lower segregation levels according to their performance, learning more practical and socio-constructivist, a lot of support to pupils with difficulties , even from their more advanced. That is, characteristics that have been frequently criticized by those with little expertise in a subject as complex as education show no qualms about a recurring issue opinions that have significant media coverage (see here ).
But PISA report data related to the comparison between countries, which are those that tend to have greater impact, they must be viewed with caution, because they come from very different cultures in which lifestyles or ethics related to work are at the antipodes. Or have something in common with a traditional Asian Buddhist or Taoist, with other northern or southern Europe, Protestant or Calvinist, the first and second-Catholic? And the recipes are valid in one context may be ineffective in others, they can achieve the same results with other measures. Thus, while some of the countries that occupy positions high ranking, such as Finland, are basically public school, in others such as South Korea's private education majority.
More interest offers the fine print of the PISA results, which often go unnoticed to the general public. Like, what are the characteristics of schools that do better? What are the variables that explain the differences between students from the same school are greater than the differences between centers, or even between countries? But above all, what is the relationship between scores on tests of language, mathematics and science with other indicators of personal adjustment, as life satisfaction or emotional problems.
latter aspect is particularly relevant when we consider that South Korea shows a high rate of suicides among primary and secondary students, which increased by almost 50% from 2008 to 2009, with the lower grades a of the main justifications. This is not surprising when you consider that students of this Asian country shows a high rate of competitiveness and stress, and great unhappiness, with many hours spent on homework, and little sleep or play. Something similar could be said of Finland, which in recent years has led European statistics on teenage suicides.
improve the academic performance of our students is a laudable objective to ensure social and technological progress, but this should not undermine the cost of their health and psychological balance. And is that a good school that meets their educational role should ensure comprehensive training of new generations, not only to achieve scale ranking positions in the PISA.
