Write 10 pages with APA style on Calorie Restriction. To further delay the process of aging and live longer, various health practices are carried out all over the world. Although there are many of these practices, only a few are systemized and supported by actual and genuine trials done by experts, which can stand scrutiny from any quarters. One of the main age delaying practices which have been studied extensively and intensively is calorie restriction.

Calorie restriction (CR) is a lifestyle choice or a dietary schedule or experimental protocol in which the total intake of calories through food is restricted, with the restriction levels based on the subject’s previous calorie intake levels. This dietary regime is consciously or unconsciously practiced by various people and importantly implemented among other living species as test subjects in labs. The scientific studies to find the correlation between restricted diets and the ageing delay was started in the first half of the 19th century. It was in 1935, the effect of food restriction on aging or life span in laboratory rats was first described by Clive M. McCay and his colleagues at Cornell University. By placing rats on a very low-calorie diet, Clive M. McCay and his team extended the outer limit of the animals’ life span by 33 percent, from three years to four. “They subsequently found that rats on low-calorie diets stayed youthful longer and suffered fewer late-life diseases than did their normally fed counterparts.” (Weindurch 2006, p. 54). Since then, CR has been regarded as a key intervention that can slow aging in many living species particularly rodents. Another trial using monkeys, which has more common genetic content with humans, has been underway and it is also showing the correlation between CR and aging. The key thing about these trials is that CR does not mean&nbsp.malnourishment because they receive enough protein, fat, vitamins and minerals to maintain efficient operation of their tissues.&nbsp.

I will pay for the following article The Viking World. The work is to be 6 pages with three to five sources, with in-text citations and a reference page. This paper aims to explore the environment in which the Vikings operated, including its history and geography, the culture which they developed among themselves, and the many different ways in which they influenced neighboring cultures. This analysis will then be used to consider how appropriate the title “The Viking World” is for a program of study on the Vikings.

The term “Viking” is often used as if it refers to one national group, but this is a mistake caused by the fact that historians from the early middle ages did not know very much about this group of people. History in those days was written down mainly by monks, and Charlemagne’s Frankish empire was the center of European civilization, and this means that the perspective on things was very biased against the Vikings.1 They were seen as barbarians, not part of the Christian world, and lumped together as the enemy. They were indeed, before the eleventh century at least, not converted to Christianity, but it is unfair to say that they were uncivilized or all the same. At least three main groups can be distinguished between them: the Norwegians, the Swedes and the Danes. Each had their specific Germanic dialect which later developed into fully-fledged separate languages. They also came from quite different geographical areas, and this is important in understanding the subcultures within Viking civilization.

Norway was then, as now, along mountainous country with many rocky inlets called fjords, and not much in the way of fertile farmland, except in the south. Fishing was therefore an important way of life for most of the population, and this led to greater and greater skill in building boats. When food and resources became scarce, for example in the frozen north where the climate did not favor human civilization, the Norsemen.
