And there's this theory from this Aussie that suggests that our intent - our real intent - is expressed by hidden messages encoded backwards in our speech. It sounds like Mumbo Jumbo, but he's charismatic and seems to have attracted quite a few followers, and if you think about it it just might not be that far out....
