“well it's actually got different parts to it first of all there's physiology we've all been anxious we know heart beating faster breathing faster okay so there's physiology that changes then there's also a behavioral change we when we're anxious we avoid the risky situation we have an impulse to to avoid if we're if we're anxious out in the open we avoid going out in the open and mice do those that do this too and then finally there's a negative quality to it which this is this is the negative valence this is the hardest part to put your finger this is the hardest part to put your finger on and it's the most mysterious and perhaps the most difficult but meaning perhaps the most difficult to experience it's most difficult to experience and it's also the most difficult to understand why we have this if we're already avoiding the risky situation why does nature also have to make us feel bad”
