Felicidad, genes y tropiezos.

Me ha sorprendido un trozo del vídeo que voy a poner a continuación. Se trata de la charla de Nancy Etcoff (investigadora cognitiva - ? - ) en TED sobre la "sorprendente ciencia de la felicidad" (sic)... A mí no me sorprende demasiado, pero bueno. De hecho, el vídeo no tienen ningún interés, pero el trozo al que me refiero es taaaaan gracioso...

Aquí el vídeo:




Aquí el párrafo que suelta en el minuto 11 literal:

"But there are ways in which our evolutionary history can really trip us up. Because, for example, the genes don't care whether we're happy, they care that we replicate, that we pass our genes on. So for example we have three systems that underlie reproduction, because it's so important. There's lust, which is just wanting to have sex. And that's really mediated by the sex hormones. Romantic attraction, that gets into the desire system. And that's dopamine-fed. And that's, "I must have this one person." There's attachment, which is oxytocin, and the opiates, which says, "This is a long-term bond." See the problem is that, as humans, these three can separate. So a person can be in a long term attachment, become romantically infatuated with someone else, and want to have sex with a third person".

Gran frase esta última.
