Whenever I do something noisy like use the vacuum or blender, I yell across the house “I’m going to make some noise now, ready? Here it comes!” And then turn on the thing.
As a result, they usually don’t even leave the room if they are in with me. They don’t get freaked out, and just go to the top of a tree and watch.
Have done so for decades with about a dozen cats and it has worked with all of them so far. I also give warning when I’m going to turn on the light, because it’s polite to not blind anyone, animal or human.
There’s no actual guarantee there will be a morbid last time with random chest pains. It could be more like the last time you burned a CD; uneventful and not really noteworthy.
Technically, heart problems only kill like…
Oof looking up those stats was depressing…
Heart disease deaths as of 2022 account for only 24% of all deaths though! So your chances of death by heart problem aren’t actually super high, especially if you don’t have existing heart problems! Yay! Its probably just a panic attack! Or gas!
The share of heart attacks as a subset of all cardiovascular disease deaths is also down, but deaths from things like hypertension are way way up, relatively, so take your meds if you have them, get your exercise, eat the veggies, do the health things.
