Remember that bit in 2312 where Kim Stanley Robinson speculates that intersex people will be longer-lived than pure males or females, leading mankind to genetically engineer for intersex traits? Well, here’s a Wired article claiming that eunuchs in ancient Korea lived substantially longer than other males.
I’m somewhat doubtful myself. It occurs to me that non-eunuch males are much more likely to die in warfare than eunuchs, which is bound to affect the data. These days trans women are much more likely to be murdered than cis men, so the opposite applies. Eventually we’ll have better data. In the meantime it amuses me that Stan might be onto something.
