While Hong Kong was more of a business center and Macau was becoming a resort destination, there were enough similarities to cross reference the data and his team was able to create an analytic left-brain quantitative prioritization model using a right brain intuitive approach to the data.
While associations are known to form based on sight, smell, and other senses -- you may remember last year's baseball game through the taste of a hot dog today, for example -- their computer model shows that the young brain cells also link through time.
