I routinely use my blue sky "Device" and it works very well for me.

The top three symptoms that I observed in high altitude workers were: 1. Forgetfulness & Confusion; 2. Irritability; 3. Fatigue & Apathy.

The problem with radio frequency (RF) exposure is not the small amount of brain tumors, is it the large amount of subtle alterations in the brain that lead to attention, confusion, insomnia and fatigue problems.

Chronic Fatigue crushes the soul.

Testing with the CPAP machine revealed that it was triggering altitude sickness symptoms after waking, specifically ‘Descent Fatigue’ during the daytime.

You do not realize how much incompetence is in the workplace until you become a supervisor.

I have to query the competence of the medical profession in the areas of mental illness and chronic fatigue.

Daily fatigue was a problem for many very high altitude workers.

At the age of 50, my Descent Fatigue is now so severe that I no longer venture to high altitudes unless I have to.
