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.
Io non ne ho idea. Per capire la risata,  dovete osservare una parte del corpo su cui psicologi e neuroscienziati  normalmente non si soffermano, la cassa toracica. Per quanto paia poco interessante, in realtà tutti usate continuamente la cassa toracica.
