It's truly amazing to watch this video about the Playboy Club in London during the schwingin' '60s and think about how all those women are now in their 70s. Nothing is more of a boner-killer than this statement: "Grandma.... uh.... is that you?"
Also, note this interesting little gem from the YouTube comments:
That's actress Barbara Bouchet. She starred in a number of Hollywood films in the mid and late 60s, including "Casino Royale" and "Sweet Charity." Did a guest shot on Star Trek TOS. Spent the 70s and 80s starring in many films in Italy. Made a brief appearance in "The Gangs of New York". Still looks pretty good for someone who is nearly seventy.
