Now, to understand laughter, you have to look at a part of the body that psychologists and neuroscientists don't normally spend much time looking at, which is the ribcage, and it doesn't seem terribly exciting, but actually you're all using  your ribcage all the time.
Mas, para entender o riso, precisamos de olhar para a parte do corpo que psicólogos e neurologistas geralmente não examinam muito de perto, ou seja, o tórax. Não e muito excitante, mas estamos sempre a usar o tórax.
