Men And Women Number Of People
512 wordsThe population of older men and women has been increasing, and therefore the number of people with osteoporosis is increasing. But in some countries, the rate of hip fractures is rising faster than the population. For example, in Malmo, Sweden the number of people older than 50 doubled since 1950, but the number of hip fractures increased seven-fold. The reasons for this secular trend in increased hip fractures are not known, but decreased physical activity may be playing a role. When discussing...

Chaos Theory Straight Lines
1,201 wordsWhere Chaos begins, classical science ends. Ever since physicists have inquired into the laws of nature, the have not begun to explore irregular side of nature, the erratic and discontinuous side, that have always puzzled scientists. They did not attempt to understand disorder in the atmosphere, the turbulent sea, the oscillations of the heart and brain, and the fluctuations of wildlife populations. All of these things were taken for granted until in the 1970 's some American and European scient...

Teenage Smoking Tobacco Industry
380 wordsOver the last five years, researchers have calculated that the teenage smoking rates have climbed tremendously. Graph number one shows a steady increase in the number of teenagers who smoke heavily. Graph number two shows how teenage smoking has made a comeback, and how the number of teen-agers smoke occasionally and who develop heavier habits has increased sharply in recent years. The tobacco industry and the critics have very different ideas why this rapid increase of teenage smoking is develo...
