As read from Inside the Outbreaks by Mark Pendergrast:
The Brown River usually flows lazily through the middle of town. But today it is a torrent carrying human bodies. Some, still alive, are gasping for air and thrashing the water.
Approaching the river to enjoy lunch on its banks, two doctors, horrified by what they see, begin to haul people out of the water. There are no signs of violence, but the victims' eyes are glazed, their weak pulses racing.
The doctors cannot keep up with the flow of bodies. They save a few and watch helplessly as the others drift beyond them.
Suddenly, one of the doctors lowers and old man to the ground and starts to run. "What are you doing?" yells the other doctor. "For God's sake, help me save these people!"
Without stopping, she yells back over her shoulder, "I'm going upstream to find out why they're falling in."
That sounds like a good job.
