Is it any wonder that America is also a country of dangerously overweight people.
According to a recent study by the National Center for Health Statistics, the number of adults characterized as overweight in the United States has jumped to an astonishing one-third of the population. Overweight in this case means being about 20 percent or more above a person’s desirable weight. Since the figures for "desirable weight" have moved upward over the last decade or so, total poundage—even at 20 percent over—may be considerable.
So are the attendant health risks. Excess weight has been linked to cardiovascular disease, hypertension, adult-onset diabetes and some forms of cancer, among other diseases.

[简答题] People and Organizations: the Selection Issue
In 1991, according to the Department of Trade and Industry, a record 48,000 British companies went out of business. When businesses fail, the post-mortem analysis is traditionally undertaken by accountants and market strategists.
