UK Business Speakers Lewis and Leyser went to London to speak at the Google Campus for the launch of David’s new book called Impulse.  They were there for 3 hours and David took a lot of questions from all the inquisitive delegates that attended.   The audience ranged from Entrepreneurs, App Developers, Designers, Students and even other psychologists.   The title of the presentation was the Hidden psychology of Consumer behavior and other authors Nathalie Nahai and Matt Watkinson also contributed and made some very fascinating speeches and interesting discussions too.
