I made some friends at Listerine and they taught me a little bit about oral care. That half of adults suffer from oral disease that the number one chronic disease among children is oral disease that we're only taking care of 25% of our mouths when brushing alone and there are more germs in your mouth than there are people on the planet.
I don't think any other city in the world... the sun doesn't shine the same way anywhere as it does in New York. And then I guess everyone's very good at hanging out. Not in a crazy way but you're just constantly interacting and learning.
