Social values also influence which choices are seen as desirable, or even possible. Consider that an average American man has a shorter life expectancy than an average American woman. There is also evidence that castration would increase men’s life spans. Should we encourage men to seek castration, as a means of prolonging their individual lives? Should we finance a public castration campaign to improve rates of mortality at the population level, in order to stem the “epidemic of virility”?
