I can feel whether a battery is full or empty based on its weight. I know it doesn’t make sense but I’ve done a blind test and it works. Empty battery is lighter.

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.

I can smell carbon monoxide.

Mould, I’m always surprised at how few people can smell when food is mouldy. I’ve had people insist the smell is a chemical smell, until we’ve found the offending mouldy item (e.g. When someone’s left a cup of coffee on their desk and gone on holiday) and I reap the glory of being right.

Back in my youth when I ruined my teeth by drinking 5-6 liters of Coca Cola a day, I could smell if a bottle was three or less months from expiration date, or if it was fresher.

Despite having tinnitus, I can still hear very subtle sounds and identify them.

• For example, a long, deep hum means a garage door is opening/closing.
• I can also hear (and feel) footsteps and movement from people around a building, even very subtle movement.
• I can also pick up on all the little creaks a building makes.

However, despite being able to hear subtle sounds, I cannot hear “no” sound or silence due to the ringing. :/

apparently no one i know can sense the chemical/marker(?) taste in artificial cherry flavouring like dr. pepper or cherry coke/pepsi

i seriously don’t know how anyone can get past that taste, so i figure people either enjoy it, or don’t notice it

I can smell iron in the soil from a distance (depending on how much there is), and if there’s a lot of iron I feel very sick, almost like I’m going to vomit, and I want to get away from it. There was one place like that where the closer I got the more sick I felt and the more iron I smelled, I could taste it like there was blood in my mouth, some months later did they start digging there and found a lot of iron.

I do not really like lager (love other types) for the same reason, the taste has a lot of iron in it especially some brands but I seem to be the only one who can taste it. I kind of rank lager as less or more irony taste lol.

Sometimes at some bars does one or multiple beers on tap taste weird and sweet regardless of type or brand. No one else of my friends seem to be able to tell. I where at a bar once where only one beer tap tasted as it should… The rest had the same sweet weird taste.

I also do not like coca-cola or Pepsi so my taste buds may just be weird.

I think I can see more colours in the stars than most people. I can also tell the northern lights are coming up earlier, so probably just low-light cone sensitivity.

A wasp died in a vent a bit ago and it smelled awful to me, but nobody else noticed.

I can smell when a woman is pregnant. I’ve shocked several friends by congratulating them before they even took a test.

I can sense when it’s time to wake up, while asleep.

It’s likely just confirmation bias, but I almost always wake up minutes before my alarm if I have a stressful or unusual appointment, like an early flight or interview.

I assume most people has this with their routine wake-up time, that the body learns when to wake up right on time… but this is like: if I usually wake up at 8:30 but now have to wake up 5:45 or 6:15 or whatever, I’ll wake up on my own right before the alarm goes off. I just need to think about it somewhat thoroughly (wake-up time and approx. how many hour of sleep until then) before falling asleep.

My nose is more sensitive than average to certain types of foul smells mostly in the poop and rotting organic material categories but also things like mouse / rodent urine, skunks, and cigarette smoke. Oh joy.

Mostly it makes me feel like I’m going crazy because I smell these things when nobody else seems to notice leading me to wonder if I’m just hallucinating the smell. But sometimes I put it to good use by being the early warning system of skunks in the area and sometimes I’m the first to notice when the milk is starting to go bad.

I can taste water, irl no one I met really can feel the different tastes of plain water but i can
