I am a sensible, in-control HCP person, able to act quickly in an emergency, keeping a cool- enough head.
I do not panic, I fight not flight (useful in a HCP).
Except when I'm at home and my smoke detectors, all three, simultaneously, are so loud they panic me. I cannot think straight. They disorient me; no one can hear shouted instructions over the din. Then, as I effect an evacuation, my hearing is a ringing mess. I can't hear.
'Kids, seriously, use the plan, get out!.... Get down, get low and go go go!'
'What? I can't hear you!'
Seriously. Great idea in principle, but not so great in practice.
