Jesse Bering explores the little known world of gerontophilia, or a young person's erotic fixation with the elderly. Though there's no link between violence and gerontophilia, Bering contemplates the fuzzy ethical considerations of those who prey on the elderly:
Elder sexual abuse is reprehensible, of course; but from a bloodless moral philosophical perspective, it does raise intriguing questions about issues related to consent, trauma, and the impact of sex crimes on victims with different psychological and physical stakes. Is the rape of a 98-year-old Alzheimer's patient—who, whether we like it or not, has only a limited awareness of what is happening, just as the perpetrator says—comparable to, say, the rape of a lucid, vulnerable child who would have to deal with the emotional scars of such sexual violence for the rest of his or her long life, or a teenager who might be impregnated? …
