A typical high school graduate has a vocabulary of 60,000 words. That equates to [learning] one word every two hours from the age of one — Steven Pinker: Linguistics as a Window to Understanding the Brain (youtube, 14:35 in for the exact quote). Its a good hour spent if you are new to Linguistics/Language & Cognition. Buy one of his books though if this floats your boat.
