• Peter Nuemann, avid tai chi practitioner, in a New York Times article about computer security, compares computing systems to biological defenses, and finds them wanting.
• In another recent article, the Times reports on computer-inflicted posture problems.For many of those years, Dr. Neumann (pronounced NOY-man) has remained a voice in the wilderness, tirelessly pointing out that the computer industry has a penchant for repeating the mistakes of the past. He has long been one of the nation’s leading specialists in computer security, and early on he predicted that the security flaws that have accompanied the pell-mell explosion of the computer and Internet industries would have disastrous consequences.“His biggest contribution is to stress the ‘systems’ nature of the security and reliability problems,” said Steven M. Bellovin, chief technology officer of the Federal Trade Commission. “That is, trouble occurs not because of one failure, but because of the way many different pieces interact....”A trim and agile man, with piercing eyes and a salt-and-pepper beard, Dr. Neumann has practiced tai chi for decades. But his passion, besides computer security, is music. He plays a variety of instruments, including bassoon, French horn, trombone and piano, and is active in a variety of musical groups. At computer security conferences it has become a tradition for Dr. Neumann to lead his colleagues in song, playing tunes from Gilbert and Sullivan and Tom Lehrer.

By one estimate that appeared in The Journal of the American Medical Association, the national cost of treating people with back and neck pain was $86 billion in 2005. And with back pain one of the top reasons for worker disability, missed work because of these aches may cost employers close to $7 billion a year, according to one study.
