What is something you can sense that few-if-any people you know can sense? Literal answers only.

    There are syringes that come prefilled with saline used to flush IVs. Some people can taste it when it’s injected, others can’t. I’m one of those who can.

    I can quickly learn to recognize specific people’s footsteps, so I can hear who’s approaching. Sometimes it doesn’t even depend on what footwear the person is wearing.

    Apparently I can hear high pitched sounds too. I’ve heard such sounds several times where people around me weren’t able to hear it, and recently I could hear an ultrasound device too, which kinda make sense since they start at around 20 kHz.

    Also, this isn’t about sensing, but I can slow my heart rate temporarily simply by holding my breath.

      Oh! I can also slow my heart rate, but I don’t hold my breath, I just beath slowly and… will it.

          Yeah, it’s not microplastics per se, just volatile organic compounds that leech into the saline over time. The smell/taste is because those VOCs want to be in the air. So when they hit your lungs, they very happily evaporate and you exhale them. So you’re just tasting your own breath. Like there may be microplastics present, but that’s not what you’re smelling/tasting, because those wouldn’t evaporate into your lungs to be exhaled.
