The writer of this passage draws our attention to -----.
Even though there have been truly significant advances
in modern medicine, health problems still abound and
cause untold misery. Although heart disease and cancer
were rare at the beginning of the 20th century, today
these two diseases strike with increasing frequency, in
spite of billions of dollars in research to combat them,
and in spite of tremendous advances in diagnostic and
surgical techniques. In America, one person in three
suffers from allergies, one in ten has ulcers and one in
five is mentally ill. Every year, a quarter of a million
infants are born with a birth defect and undergo
expensive surgery, or are hidden away in institutions.
Other degenerative diseases such as arthritis, multiple
sclerosis, diabetes, and chronic fatigue afflict a
significant majority of Americans. Further learning
disabilities make life miserable for seven million young
people and their parents. These diseases were
extremely rare only a generation or two ago. Today,
chronic illness afflicts nearly half of all Americans and
causes three out of four deaths in the United States.
