There is a huge difference in the body patterns of old age people and young people. Young persons have an immune system that is capable of preventing diseases and it is not affected by most of the disease. In some case if it is affected by some severe disease it easily recovers by having drugs or medicines. But older people need acute care and nursing to recover as their immune system is very weak.
Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results. Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications. The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
