Misplaced your keys? Forgot where you parked? Can’t remember your age. Okay, that one is not a memory issue, just wishful thinking. Can’t spell anymore?

There’s hope.

Joshua Foer, in his new book, “Moonwalking With Einstein,” says that our memories are indeed improvable. There are established techniques–pioneered by the Greeks and Romans–to help train the brain.

Quick, no peeking, who wrote the book?

It seems that the brain remembers visual imagery and erotic, exotic and exciting imagery best. “Evolution has programmed our brains to find two things particularly interesting, and therefore memorable: jokes and sex. Linking the erotic with what you are trying to remember improves recall.

Apparently, gazing lovingly at his own various and assorted parts, Rodin’s The Thinker already knew this technique.

So then, close your eyes and try to recall some, any, all erotic, exotic experiences you’ve had.

Try again.

Need I say more?
