Description: Each year, one six-day annual event in the United States attracts 5,000 scientists as well as other individuals with a strong interest in science. The Society of Actuaries was formally represented this year for the first time at the event, the annual meeting of the American Association for the Advancement of Science [AAAS], held Feb. 12-17, 1998 in Philadelphia. An eminent panel discussed the 1997-98 SOA research project, 'Impact of Mortality Improvement on Social Security: Canada, Mexico, and the United States.' The SOA’s session was entitled 'Social Security in the NAFTA Countries: What if People Stop Dying?' This article summarizes that presentation.
