How do "stop breathing" or "stop blinking" work for a vampire?

Vampires do no need to breath that is fact, they do not need oxygen to work as us do, so they do not need to breath, thay can not be suffocated or air privated to kill them. similar with blinking, they usally do not need to blink since they dont need to keep their eyes wet. So Imagine you being a Kindred yo have al most 150 years, in this case clan does not really matter as long you have your lungs and eyelids. if a younger kindred asks you "how and when you stop breathing and blinking" what would you say?
