Short Answer Questions
Passage 1
A man's skin is thicker than a woman's and not nearly as soft. The thickness prevents the sun's radiation from getting through, which is why men wrinkle less than women do.
Women have a thin layer of fat just under the skin and there is a plus(有利因素)to this greater fat reserve. It acts as an invisible fur coat to keep a woman warmer in the winter.
Women also stay cooler in summer. The fat layer helps insulate them against heat.
Men's fat is distributed differently. And they do not have that layer of it underneath their skin. In fact, they have considerably less fat than women and more lean mass. Forty-one percent of a man's body is muscle compared to thirty-five percent for women, which means men have more muscle power. When it comes to strength, almost 90 percent of a man's weight is strength compared to about 50 percent of a woman' weight.
The higher proportion of muscle to fat makes it easier for men to lose weight. Muscle burns up five more calories a pound than fat does just to maintain itself. So when a man goes on a diet, the pounds roll off much faster.
For all men's muscularity they do not have the energy reserves women do. They have more start-up energy, but the fat tucked away in women's nook sand crannies(隐匿处)provides a rich energy reserve that men lack.
Cardiologists(心脏病专家)at the University of Alabama who tested healthy women on treadmills(单调而又劳累的活)discovered that over years the female capacity for exercise far exceeds the male capacity. A woman of sixty who is in good health can exercise up to 90 percent of what she could do when she was twenty. A man of sixty has only 60 percent left of his capacity as a twenty-year-old.

Passage 2
Chronic disability is affecting people more frequently at younger and younger
age. According to the National Center for Health Statistics, the percentage of children under 17 years of age who are limited in activity due to chronic conditions increased by 86% from 1967 to 1979.
Mental disease is affecting more and more people. The National Institute of Mental Health estimated in 1984 that one in every five Americans had a mental disorder. This same study revealed that, during a six month period,8.3% of Americans suffered from an anxiety disorder, 6.4% had an alcohol or drug problem, and 6% had a mood disorder.
In addition to these various trends, one of the more significant facts that will affect the future of health care is that a large percentage of the population will be over 65 years old. According to projections by the U.S. Bureau of the Census, the size of the American population over 65 in 1985 will have doubled by 2030.
Futurists generally assume that twenty-first century medicine will include new and more powerful drugs and various innovative technological interventions. However, futurists tend to ignore the serious problem presently arising from conventional medications. According to 1986 statistics, the average American receives 7.5 prescriptions a year. This is a particularly frightening number because we all know people who have not been prescribed any medications in the past year, which means that someone else is getting their 7.5 drugs.
