A phrase I have long kept- deep - that emerges as pertinent for us now:
Aviation term:
"The Time of useful Consciousness"
"the maximum time the pilot has to make rational, life-saving decisions and carry them out at a given altitude without supplemental oxygen,
before blacking out."

potential dream accomplice..
Intriguing :
Altitude
TUC decreases rapidly at higher altitudes. For example, at 18,000 feet, TUC is usually around 15 minutes, but at 25,000 feet it's usually
3–10 minutes, and at 40,000 feet it's only a few seconds.
So fly low..

Symptoms of Hypoxia High-altitude flying can place a pilot in danger of becoming hypoxic. Oxygen starvation causes the brain and other vital organs to become impaired. The first symptoms of hypoxia can include euphoria and a carefree feeling.
Stay engaged
As hypoxia worsens, the field of vision begins to narrow and instrument interpretation can become difficult. Even with all these symptoms, the effects of hypoxia can cause a pilot to have a false sense of security and be deceived into believing everything is normal.
...anxiety further aggravate[s] the problem. Hyperventilation can lead to unconsciousness due to the respiratory system’s overriding mechanism to regain control of breathing. Pilots encountering an unexpected stressful situation may subconsciously increase their breathing rate. If flying at higher altitudes, either with or without oxygen, a pilot may have a tendency to breathe more rapidly than normal, which often leads to hyperventilation. Since many of the
symptoms of hyperventilation are similar to those of hypoxia, it is important to correctly diagnose and treat the proper condition. If using supplemental oxygen, check the equipment and flow rate to ensure the symptoms are….
45,000 feet - 9-15 seconds
30,000 feet 1 - 2 minutes
22,000 feet - 5-10 minutes
20,000 feet - 30 minutes or more
"Breathing normally is both the best prevention
and the best cure for hyperventilation. In addition to slowing the breathing rate, breathing into a paper bag or talking aloud helps to overcome hyperventilation. Recovery is usually rapid once ….."
Inversion Illusion
An abrupt change from climb to straight-and-level flight can stimulate the otolith organs enough to create the illusion of tumbling backwards, known as “inversion illusion.”
The disoriented pilot may push the aircraft abruptly into a noselow attitude, which may intensify this illusion.
Elevator Illusion An abrupt upward vertical acceleration, as can occur in an updraft, can stimulate the otolith organs to create the illusion of being in a climb.
This is known as “elevator illusion.” The disoriented pilot may push the aircraft into a nose-low attitude.
An abrupt downward vertical acceleration, usually in a downdraft, has the opposite effect with the disoriented pilot pulling the aircraft into a nose-up attitude. Visual Illusions Visual illusions are especially hazardous because pilots rely on their eyes for correct information.
Two illusions that lead to spatial
disorientation, false horizon and autokinesis, affect the visual system only. False Horizon A sloping cloud formation, an obscured horizon, an aurora borealis, a dark scene spread with ground lights and stars, and certain geometric patterns of ground lights can provide inaccurate visual information, or “false horizon,” when attempting to align the aircraft with the actual horizon. The disoriented pilots as a result may place the aircraft in a dangerous attitude,"
