title: Reliability of inferred age, and coincidence between inferred age and chronological age.
abstract: Outdoor research is restricted by many factors. The age inference was one of the biggest problems for the outdoor researchers. We have investigated the reliability of inferred age for the Japanese people, and took out the estimation formula for the age, even if it was based on the inferred age. The age classification was the most popular method for this purpose, and there were many classifications. We took the classification of young, middle aged, and elderly groups, in which classification of the SDs were rather small, that is, 4, 5, and 7 years for the young, middle aged, and elderly age groups, respectively.
