[A troublesome privilege--physicians' loss of the right to prescribe].

This study includes 32 doctors (31 men) who in 1990 had lost or given up the right to prescribe habit-forming drugs. 11 were hospital doctors, while 21 were either in private practice or held other posts. The records of the Norwegian Board of Health were reviewed.

[Forensic psychiatric examinations of the mentally retarded].

3,343 forensic psychiatric examinations were recorded in Norway from 1980 to 1996. 294 patients were diagnosed as mentally retarded. The annual number of mentally retarded persons increased during the observation period, but the relative percentage remained stable.

[How old can one become?].

We recorded the highest age at the time of death for both men and women in Norway for the years 1970 to 1995. During this period longevity increased by approximately one year; for women from 106 to 107 years and for men from 105 to 106 years. Based on Gumbel's theory, we have estimated the most probable highest age for the next 10, 20, and 100 years.
