Malcolm Gladwell, author of the hit book 'The Tipping Point' gives an incredibly interesting and informative talk on the grouping of people when it comes to the manufacture and retail of various food products such as tomato sauce and coffee. Gladwell explains that when it comes to pasta sauce, people can be broken down in to three main groups: regular tomato, spicy and extra chunky!
