"when you have an object close to your face, it’s registered as a threat" Ok I wonder to what extent the flight / fight response can be unconscious and not noticed And I get that FoF can be triggered. But from seeing the phone it can't be nearly as much as with seeing a bear coming at you can it? I'm also curious what kinds of objects do that, and why does the phone do it and not something else? Like would reading the news trigger that? Playing a game of chess? I think I will ask Perplexity AI on those later
