Last August, Dr. Scott Jolley came home at 3 am from a busy emergency room shift looking pale, far older than his 55 years. It was the middle of the Covid-19 pandemic, and he had been the only physician on duty at his hospital in Salt Lake City, Utah. One of his patients had gone into cardiac arrest after Jolley removed his personal protective equipment to meet his next patient. Jolley, athletic with dusty brown hair, had to frantically gown up and run back to perform a resuscitation. The patient survived, but Jolley felt agitated.
