When a woman called 911 complaining of difficulty breathing, my husband, Glenn, and his partner—both EMTs—rushed to her home. Glenn placed a sensor on her finger to measure her pulse and blood oxygen. Then he began to gather her information. "What’s your age?" he asked.
"Fifty-eight," answered the patient, eyeing the beeping device on her finger. "What does that do?"
"It’s a lie detector," said Glenn with a straight face. "Now, what did you say your age was?"
"Sixty-seven," answered the woman sheepishly.
