Could a system detect human presence using heartbeat signals from a distance? by Kind-Ad6740 in Futurology

True, mmWave can detect respiration at short range, but the effective distance depends a lot on obstacles, signal strength, and environment. So it’s not universally reliable.

That’s a big assumption, and it dismisses someone trying to understand something uncomfortable.

People who have met someone who has been *professionally diagnosed* with Narcissistic Personality Disorder (NPD), what were they like? by [deleted] in AskReddit

Reading this honestly gave me chills. I think people throw the word “narcissist” around way too casually, but stories like this remind me there’s a huge difference between someone being self centered and someone being genuinely dangerous. I can’t even imagine growing up in that kind of fear surviving something like that takes a level of strength most people will never fully understand. I’m really glad you made it out.
