Yo siempre que voy a una librería me dan muchas ganas de cagar. Siempre se lo atribuí a la emoción ñoña de tener tantos tantísimos libros alrededor para hojearles y ponerles mis pezuñas encima y recientemente me enteré que no estoy sola. Es un fenómeno conocido como "Mariko Aoki".
Una lista de 10 hechos entretenidos relacionados con la caca aquí http://listverse.com/2014/01/16/10-b...ts-about-poop/If a trip to the bookstore sends you doing the penguin walk straight to the bathroom, you aren’t alone. In 1985, a woman named Mariko Aoki wrote an essay for an issue of the Japanese magazine Han no Zasshi explaining her uncontrollable urge to go to the bathroom while perusing the shelves at bookstores. Surprisingly enough, the article resonated with the public, with others claiming to have experienced this as well.
Whether this “phenomenon” exists outside of Japan is up for debate. Theories supporting the veracity of this claim are wide-ranging, with some claiming that perhaps the smell of the ink, paper, or binding glue has a kind of laxative effect. Others say that the bodily position assumed by looking at books eases the body into wanting to poop. Of course, it may simply be that the act of reading (which the majority of people do while sitting on the toilet) subconsciously triggers a physiological response.
