This week on Always Wondered, we explore your brain’s favorite pastime - Phobias!  Why does something that seems totally harmless suddenly have our knees knocking?  We’ll try to make sense of it all.  Also, how come one of your shoelaces always comes untied before the other?  Science has actually studied this, and we’ll have the details.  Plus, we dive into one of the great mysteries of grocery shopping.  Why do hot dogs come ten to a pack, but buns only eight to a pack?  So join host Rick Peterson as he answers more of the questions you’ve Always Wondered about.
