One of the biggest changes since 1990 is the degree to which bioterrorism has become a public health priority. Although there had long been concern about vulnerability to biowarfare and bioterrorism, the anthrax episode in the fall of 2001 made it clear that the concern is no longer theoretical. Until very recently, the important role of public health at the frontlines of bioterrorism preparedness was unrecognized. Although concern about emerging infections has helped stimulate funding for the chronically underappreciated public health system, the threat of bioterrorism motivated the first real infusion of new money into public health in decades.

"Social withdrawal" refers to the state of disorder into which an increasing number of youngsters seem to fall these days. Socially withdrawn kids typically lock themselves in their bedrooms and refuse to have any contact with the outside world. They live in reverse: they sleep all day, wake up in the evening and stay up all night watching television or playing video games. Some own computers or mobile phones, but most have few friends. Their funk can last for months, even years in extreme cases. They find it extremely painful to communicate with the outside world. This painful communication prevails throughout our society: in the family, in the community, between management and employees, between the government and the people. Miscommunication has pulled people further apart and caused a whole raft of social problems.
