And that's actually my eye, and again this video was taken right after my daughter was born, so you can see I wasn't getting too much sleep.  Even when a person is sitting still, there's a lot of information we can extract about their breathing patterns, small facial expressions.
Dit is mijn oog, opgenomen vlak nadat mijn dochter was geboren, dus je kunt zien dat ik slaap tekort kwam.  Zelfs wanneer iemand stil zit, is er veel zichtbare informatie over hun ademhalingspatroon en kleine gezichtsuitdrukkingen.
