the lyme disease wars

These ticks are kind of remarkable. First they get on you and they spread some antihistamines and some other little numbing medications so that you don’t notice the bite, then they excrete something called ‘cementum,’ which is sort of like a glue, so that they can fasten onto you. Then they get their jawbones in there and go for a ride.
