Slate has the crazy story of a 95-year-old woman and 82-year-old man both suffering from dementia who struck up a sexual relationship at the assisted-living facility where they lived until his family tore the couple apart.
Apparently, seeing your elderly dad get a hummer can really loosen your screws. According to the article:
Bob's family was horrified at the idea that his relationship with Dorothy might have become sexual. At his age, they wouldn't have thought it possible. But when Bob's son walked in and saw his dad's 82-year-old girlfriend performing oral sex on his 95-year-old father last December, incredulity turned into full-blown panic. "I didn't know where this was going to end," said the manager of the assisted-living facility where Bob and Dorothy lived. "It was pretty volatile."
This harkens back to something we've already taken pains to mention--old people...still people. They screw, play the Wii, write, direct and produce short films, and sing Hey Ya" in choir with their friends.
They also review the Sex and the City movie on YouTube.
