> This is interesting to me. It does make some evolutionary sense but at the same time, i wake up every morning and look at my girlfriends face, hopefully that does not subconsciously trigger the same response. Yeah, exactly. If my adult brain can distinguish between my wife's face and a bear, or my pillow and bear, why can't it distinguish between my phone and a bear? Plus, the phone is an object I hold in my hand. Is TFA saying that other objects I hold in my hand and bring close to my face so I can get a good look at them register as threats? It reads like nonsense to me.
