We haven't found a "buy" button inside the brain, we can't tell whether someone is lying or in love just by looking at their brain scans, and we can't turn sinners into saints with hormones.
No hemos encontrado un botón de "comprar" dentro del cerebro, no podemos decir si alguien miente o está enamorado sólo mirando sus encefalogramas, y no podemos convertir pecadores en santos con hormonas.
