A college physics professor was explaining a particularly complicated concept to his class when a pre-med student interrupted him.“Why do we have to learn this stuff?“ the frustrated student blurted out.“To save lives,“ the professor responded before continuing the lecture.A few minutes later the student spoke up again. „So how does physics save lives?“The professor stared at the student without saying a word. „Physics saves lives,“ he finally continued, „because it keeps the idiots out of medical school.“
