“The patient looks around frantically. She is sobbing, panicking, overwhelmed by anxiety. She says she can't breathe; her lungs are about to collapse; her heart is about to stop. She feels like she is going to die.

The doctor asks: "Do you think you could exercise strenuously right now?"

She doesn't know, she just feels so bad. "Why don't we find out?" The doctor asks her to try some jumping jacks.

"Could you do this if you were dying?" he asks the patient. "Can you see yourself in an emergency room doing jumping jacks?" Hesitantly, the patient begins to laugh. Soon she's belly laughing.”
