　　The concept of personal choice in relation to health behaviors is an important one. An estimated 90 percent of all illness may be preventable if individuals would make sound personal health choices based upon current medical knowledge. We all enjoy our freedom of choice and do not like to see it restricted when it is within the legal and moral boundaries of society. The structure of American society allows us to make almost all our own personal decisions that may concern our health. If we so desire, we can smoke, drink excessively, refuse to wear seat belts, eat whatever food we want, and live a completely sedentary life-style without any exercise. The freedom to make such personal decisions is a fundamental aspect of our society, although the wisdom of these decisions can be questioned. Personal choices relative to health often cause a difficulty. As one example, a teenager may know the facts relative to smoking cigarettes and health but may be pressured by friends into believing it is the socially accepted thing to do.

Very, very occasionally, perhaps twice in a hundred years, sufficient rain falls to form a deep lake that lasts a month or more. In this case, the species passes through two cycles of growth, egg-laying, and death. Thus, on such occasions, the species multiplies considerably, which further ensures its survival.

      To some, the thought of having to write an assigned number of pages, often more than ever produced before, is disconcerting. To others, the very idea of having to work independently is threatening. But there is no need to approach the research paper assignment with anxiety, and nobody should view the research paper as an obstacle to overcome. Instead, consider it a goal to accomplish, a goal within reach if you use the help this book can give you.
