 I'm sure you're aware of this or maybe you haven't heard, but in dealing with our phones, what we are now discovering is that a lot of the things, the games actually have them, they've carefully designed the games to create a dopamine hit to cause you to come back again and again and again. They designed these games to be addictive. If you're not aware of that, that's very true. It's also true of, for instance, the way the videos now work on slot machines.
