Pilots practice emergency scenarios and emergency procedures umpteen times as part of training the brain (& body) to go through the actions with less denial chatter and fear . . . for some/many pilos it works wonders, but for others they still freeze or go into "nah, it can't be THAT" as part of their calculus.
Human behavior still as unpredictable as anaphylaxis. Not good that we have BOTH working together when in the grips of emergency.
Besides needle phobia, there seems to be -- in teens for sure -- EMBARRASSMENT phobia. Don't want to call attention to myself or my medical predicament.
(Ambulance ride with bells and whistles? Cost and negative attention to self also factor in here . . . )
But I digress.
I'd sure opt for nasal epinephrine if available. Not sure if either of my kids would go for that given how bad they hate (refuse) other nasal sprays/drops.
Question: How about eyedrops? Would that work?
