Ana, i was hoping that you would tell us a bit more about how these emotions are grouped in clusters. They're grouped in particular ways, right? And they relate to each other in particular ways - which i first heard of from you. I'm hearing you describe this hans an thinking that that sounds like the business model for a lot of the social networks. Rat, well, i mean, they absolutely the trigger these emotions and they play with it, and it's actually like a drug. What it does is it could completely disconnect you from reality.
