A person exhibiting confusion at high altitude will commonly forget to take oxygen to alleviate it.

Industrial liquid gas containers were left open and venting gas into the indoor environment in high altitude astronomy. On reflection, I realized that I routinely observed mental and physical effects that match those of a low oxygen environment in staff that I supervised.

Every observatory summit office that I was based in had no windows in high altitude astronomy. My workdays were spent bathing in artificial florescent light.

High altitude observatories are commonly constructed with few to no windows, meaning that their staff are typically natural light deprived during their work day.

I though that it was strange that people were changing gender in high altitude astronomy until I read Dr. John Nash Ott's books and his discussions about how he was changing the gender of plants and animals using distinctly different spectrum's of light from commercial lighting products. The spectrum of light at high altitudes is distinctly different to that at sea level.

Ultraviolet light is a known carcinogen and can affect human health in many ways that are only just starting to be understood.

Mercury poisoning will take you into a very dark place and chelation will bring you back into the light.

Until I see President Trump routinely flying on a Boeing 737 Max, I will be avoiding it.

It was normal to drink two pots of coffee during an extreme night shift.
