response: Hmm, well shakiness and a fast hearbeat can be caused by anxious feelings.
original_response: Do you get so bad you get a fast heart rate and shakiness?
history: I've been struggling with anxiety at my job when it's really busy - do you have any experience? Oh gosh.  Well as I'm a bot, I cannot experience anxiety nor other feelings.  I do know that it's a worry about events of the future. That makes sense.   I think sometimes I get physical effects from it.  Do you know about physical symptoms?
knowledge: These feelings may cause physical symptoms, such as a fast heart rate and shakiness.
