Yellow posted... Do you live in Afghanistan or something?
My fight or flight response is modem noises. One time a bunch of angry dogs jumped the fence and ran at me and I just looked at them and walked away. In elementary school a kid ran up to me and punched me because I was destroying him in dodgeball and I just looked at him, then he stormed off. When I play video games with friends or by myself I have no reaction to any danger and I usually die first. If I'm playing Rust and get attacked I just stand there and guilt trip the attacker for killing me while I die.
I vaguely remember someone threatening me at one point and I didn't reciprocate it at all, and they just got frustrated and told me to gtfo of there.
No, but I do have several phobias and am easily sensitive to stimuli.
It's good that seemingly nothing rattles you.
