apparently a tiny piece of brain in your prefrontal cortex has to give you constant affirmation of the fact that you are, for better or for worse, alive and if it stops doing so (sometimes due to micro stroke killing that specific part of your brain, more usually just buildup of antivirals due to kidney problems) and suddenly the rest of your brain is just 100% certain that you have passed away

stranger yet, hiccups function on the same exact principle
