A survey team of Professor Kenji Horiguchi and Professor Masahiko Gennma from Waseda University conducted a questionnaire survey on healthcare costs data of the latter-stage elderly for farmers in Honjo City. As a result, farmers' late-stage elderly medical expenses remained about 70% of non-farmers, and the average life expectancy was found to be 8.2 years for males and 1.6 years for females.
