Doctor Ivan Schwab in California is one of the people, one of the main people, who helped answer the question, "Why don't woodpeckers get headaches?" And it turns out the answer to that is because their brains are packaged inside their skulls in a way different from the way our brains, we being human beings, true, have our brains packaged.
Dr. Ivan Schwab din California e unul dintre oamenii care au răspuns la întrebarea: „De ce nu suferă ciocănitorile de dureri de cap?” Iar răspunsul se pare că e așa: creierul lor e așezat în craniu altfel decât al nostru, altfel decât e așezat creierul oamenilor.
