Recently I was doomscrolling on Youtube, clicking random videos, until I stumbled across this channel. And like. Apparently this person's whole channel consists of heartbeat sounds, "heart torture", heart shots, pulse, everything heart related. There's nothing else on there. And that's how I discovered that, apparently, there's a thing called "cardiophilia", basically a fetish for hearts?? And this kind of thing is called "dark cardiophilia", because apparently this person likes making the heart suffer??? These people record their own heartbeats, make their own heart race on purpose, measure their record BPM, make their heart skip on purpose... You learn something new every day, I guess???
