Most people will tell you they want to kill you without directly saying it with words. Energy / tone of voice / body language… words actually don't have much meaning unless you're trying to explain math, technology or history.
Don't think so. Typhoid. I get really sick after being around Indians, even if talking to me from 6-8ft distance I get putrid taste in my mouth that lasts for days or weeks sometimes. It tastes like what they smell like. To be fair, most people are really sick in general, Caucasians emit this foul fungus taste that I have no comparison to make it to. Asians and middle-easterners are the most hygienic ppl I've met in general.
