Very high altitude extreme night shift work is a class 2A carcinogen that may result in lifelong disabling sleep disorders, high cholesterol, radiation sickness and heart, lung and brain damage.

Extreme night shift work in high altitude astronomy is easily avoidable by using a split night shift where the first night shift starts before sunset and finishes at midnight and the second night shift starts with a new fresh person working through to after sunrise.

Research suggests that sea level adapted humans that work at the very high altitude 13,796 feet summit of Mauna Kea may eventually develop sleep apnea and fatigue from the low oxygen environment.

The altitude of any relation is possible through discourse.

At the age of 46 I was starting to see the appearance of rainbow halos and starbursts around bright nighttime lights, problems reading small print, focusing issues with my eyes, and image recognition issues. I had been exposed to bright high powered 20 watt scattered sodium LASER light a decade earlier in very high altitude astronomy.

At the age of 45, most days in Tucson were spent feeling like I was on the summit of Mauna Kea, as I was exhibiting debilitating health symptoms that corresponded to what I saw at very high altitude. I was later to find that I had erratic low blood oxygen levels after almost a decade of high altitude work.

During my time in high altitude astronomy, I routinely witnessed workers breathing medical oxygen, industrial carbon dioxide, nitrogen and helium gas as part of their daily work routine.

If you are looking for a career that may induce a myriad of health conditions into you, I can recommend working at the 13,796 feet very high altitude summit of Mauna Kea, Hawaii, USA.

At the W.M. Keck Observatory on the very high altitude summit of Mauna Kea, there was no routine monitoring of mental functioning, blood oxygen levels, blood pressure or heart rate of workers.

The amount of people I met that had heart problems surprised me in high altitude astronomy. I had not seen it in other fields. After a decade of working at high altitudes, I was also diagnosed with a heart problem.

After a decade of working in high altitude astronomy the medical profession discovered that I had a hole in my heart, erratic low blood oxygen levels and brain issues. Heart, lung and brain problems appear to be long term known adverse health aspects of high altitude work and unnatural electromagnetic radiation exposures.

The summit of Mauna Kea should never have been developed as it is not safe for humans up there. I am now locked into an endless loop of doctors visits for what appears to be classic very high altitude heart, lung & brain damage because I was unfortunate enough to have worked there.

High altitude astronomy is a strange world of oxygen starvation, sleep deprivation and radiation sickness.

As a sea level adapted human, I am more fearful about the radiation levels on top of high altitude mountains, mile high modern cities and inside jet aircraft than from nuclear reactors and bombs, as that is where I get the most radiation exposures in the modern world.

We are the sum total of our choices.

I regard taking healthy sea level adapted children to the 13,796 feet very high altitude summit of Mauna Kea as a form of child abuse.

There is a lot of willful incompetence in high altitude astronomy that is in the process of coming to light.

The higher you getthe more light you catchbut too much altitudelets you run out of air... ...because you might not belong there

Never trust a high altitude astronomer.

My memories of my time in high altitude astronomy indicate that there were no oxygen concentration monitors or alarms in the areas that liquid nitrogen was in use at the high altitude astronomical facilities where I had worked.

When I was instructed to use medical oxygen to do my job at the W. M. Keck Observatory from 2001 to 2006, I was never told about the legal health information that is now posted on oxygen cylinders. My memories of the green medical oxygen cylinders that we would use daily is that they had no information on them and we were never given a recognised legal oxygen administration training course for routine daily use or a medical prescription from a doctor. We were shown the three oxygen cylinders at the facility and told to use them whenever we developed headaches, which was multiple times daily. It was common to find all three oxygen cylinders in use by other very high altitude workers and to have to line up to get a turn on the magical medical gas.

In high altitude astronomical facilities we routinely discharged large amounts of nitrogen gas into closed spaces. We were never informed by the astronomy management team about the abnormally low oxygen environments that the use of liquid nitrogen creates, how long term exposure to it manifests itself in human health and the resulting abnormal mental behaviors.

The toxicity of medical and industrial gas to the human depends on where it is used. A gas that is regarded as safe in a well ventilated environment at sea level may be a toxic gas in an indoor environment at high altitude.

For the purpose of human health, it appears that it is wise to work and live below 4,900 feet.

One of the biggest lies that is currently being told in the USA workplace is on the legally required OSHA poster: All workers have the right to a safe workplace.

When I saw how many people were objecting to the construction of the Thirty Meter Telescope atop Mauna Kea, I realized that there needed to be an open and honest discussion about the toxicity of the 13,796 feet very high altitude summit and the health and safety issues of astronomical observatories.

One of my astronomy managers used to tell me that liquid nitrogen was harmless and was just liquid air. He would pour it onto his bare hands to demonstrate how safe he thought it was. I was later to realize that incompetence was a feature of high altitude astronomy.

When I worked in high altitude astronomy, the worst sickness that I experienced was not at the 13,796 feet very high altitude summit of Mauna Kea Observatory (MKO) in Hawaii, it was at Kitt Peak National Observatory (KPNO) in Arizona at the much lower altitude of 6,875 feet. Due to my very high altitude experiences, I knew that this strange sickness was not primarily caused by altitude sickness and was most likely Sick Building Syndrome (SBS). After reporting various behavioral problems in all of the staff to the management team, my contract was not renewed, I was unable to legally protect the health and safety of the workers that I was responsible for, troubleshooting of this environmental problem stopped and I left in a sickened state for my next position before I could find the root cause.

Very high altitude observatories are a known worker health hazard.

When I worked at the W. M. Keck Observatory on the 13,796 feet very high altitude summit of Mauna Kea, we would routinely be engulfed in cold clouds of helium and nitrogen gas as we discharged it into the video camera systems daily. The management team never warned us that we were in a hazardous oxygen deprived environment during this activity that was known for its ability to adversely affect physical and mental health, and possibly bring on death by asphyxiation.

Thanks to President Obama, I am able to get medical treatment in the USA for the long term effects of very high altitude sickness and unnatural electromagnetic radiation exposures.

The biggest surprise that I had during my time in high altitude astronomy was being prevented from arranging a free Occupational Safety & Health Administration (OSHA) onsite evaluation to assist with bringing the observatory into OSHA compliance by the upper management team that I reported to.

The lasting physical and mental health effects of long term very high altitude exposure appear to be remarkably similar to daily heavy smoking.

I have been through the OSHA system twice and I can confirm that I did not have the right to a safe workplace or whistle-blower protection on either occasion.

A sincere attitude of gratitude is a beatitude for secured altitudes. Appreciate what you have been given and you will be promoted higher.

Gratitude is an excellent attitude which can lift you to a greater altitude if you put it on as a vesture.

Attitude with gratitude supported by fortitude will take you to the next altitude!

Everything seems so small, so trivial, when you're on the right altitude.

A healthy person that uses medical oxygen to perform their job on a daily basis should expect to eventually become a sick person.

Altitude sickness, unregulated drugs and medical gas enabled workers to become drug abusers/addicts

I consider myself fortunate that I spent three years working at 7,775 feet before spending five years working at 13,796 feet on the summit of Mauna Kea. I can only wonder how much more severe my long term very high altitude sickness could have been without the initial adaptation to the lower altitude.

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.

When discharging industrial gas into the indoor environment in high altitude astronomy, we never wore breathing respirators that fed us oxygenated air at above the legally required 19.5% oxygen levels.

When I worked in astronomy, I routinely observed young college and university students working with liquid nitrogen and breathing nitrogen gas as they discharged it into the indoor environment at high altitude.

Astronomy staff that routinely discharged industrial gas into the indoor environment at high altitudes did not wear oxygen deficiency monitors or protective breathing respirators.

The scandal with the Thirty Meter Telescope (TMT) atop Mauna Kea is how it managed to obtain a construction permit to build a manned telescope in a known biologically toxic environment to workers. How many more people need to die, get injured or develop long term very high altitude sickness that will last a lifetime?

The velocities and forces involved in anything at orbital altitudes were enough to kill a human with just the rounding error. At their speeds, the friction from air too thin to breathe would set them on fire.

Very high altitude astronomy only works by ignoring established biological science

When I worked on the 13,796 feet very high altitude summit of Mauna Kea we were advised to only use the medical oxygen after the daily headaches appeared and that just 15 minutes use was all that was needed to clear up the headaches for a while before we would need it again. We were not advised to use medical oxygen continuously as the Federal Aviation Regulations advises pilots to do. We were not advised to use pulse oximeters to monitor our blood oxygen levels or that the company medical oxygen should have been routinely administered only with our doctors prescription.
