TER General Board
I have heard it slightly different, based solely on continents. Something like this:
When she's in her teens, she's like Africa, virgin and unexplored.
When she's in her twenties, she's like North America, obsessed with nothing but capital gain.
When she's in her thirties, she's like South America, incapable of controlling herself thanks to her newfound sense of freedom.
When she's in her forties, she's like Asia, exotic and enticing, but probably also overpopulated and infected by strange diseases.
When she's in her fifties, she's like Europe, mature and sensual, aged like a fine wine ... with all the wrinkles.
When she's in her sixties, she's like Australia, with unpredictable oddities and curiosities going on down under.
And when she's in her seventies or older, she's like Antarctica: it's down there, but nobody cares.
And then the man thing:
When a man is like a continent, it's IN.
