A New Definition of "Small"
(Boring background information: Lyme disease is carried by the deer tick. It's really small.)
Evaluating the possibility of Lyme disease over the phone:
"How big was the tick that bit you?"
"Smaller than the group number on an Aetna ID card?"
"About that size."
"Ah. Please come right in for a blood test."
Moral of the story: Could they possibly print the group numbers on an Aetna ID card *any* smaller!?!
