I have passed through some jobs that were real lemons.

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

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.

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.

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 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.

This was my Mauna Kea experience: 1. Hire worker and do not disclose the full range of the biological toxicity of the very high altitude facility to them. 2. Let the worker get sick and start using their earned sick time. 3. Harass the sickened worker out of the company. 4. Hire an unsuspecting healthy worker to replace them.

During almost a decade in high altitude astronomy, I developed a strong dislike for the upper management teams through experience.
