Three paramedics were boasting about
improvements in their respective ambulance team's response times.
"Since we installed our new satellite
navigation system," bragged the first one, "we cut our emergency response time
by ten percent."
The other paramedics nodded in approval.
"Not bad," the second paramedic commented. "But by using a computer model
of traffic patterns, we've cut our average ERT by 20 percent."
Again, the other team members gave their
congratulations, until the third paramedic said, "That's nothing! Since our ambulance
driver passed the bar exam, we've cut our emergency response time in half!"
