Quote by Paul Ehrlich

"The microbe is so much smaller than ourselves that we can easily forget the fact that it stalks us all the time, waiting, and watching for the moment when we lay down our defense."

"In science there are no shortcuts to truth."

"The side-chain theory explains the formation of antibodies."

"Medicine is a science of uncertainty and an art of probability."

"Never let fear stop you from chasing your dreams."

"Courage is being afraid but doing it anyway."

"Sometimes you gotta do what you gotta do."

"Sometimes you have to be the monster to stop the monsters."
