Korean eunuchs outlived uncastrated peers - "The average lifespan of eunuchs was 70.0 ± 1.76 years, which was 14.4–19.1 years longer than the lifespan of non-castrated men of similar socio-economic status." The study made use of the Yang-Se-Gye-Bo (養世系譜, 양세계보), a genealogy record of Korean eunuchs, and cross referenced the Annals of the Chosun Dynasty and Diary of the Royal Secretariat. The Annals and the Diary are official records of the daily activities of the Chosun government and the King.
