““These interests are stronger than pastimes and stronger than hobbies. A person might enjoy model trains and fill up his or her basement with an extravagant layout, but this is merely a hobby in comparison to an autistic who might have an interest in, say, electric can openers. An autistic with such an interest might not only try to accumulate a collection of electric can openers, but will try to get the specifications for each and every electronic can opener that was ever made, as well as the information on the original inventor and the people who have since made modifications to the design of the original product.””
