Working a 40 hour work week is a very shallow and unfulfilling experience for many people.

Many people over forty have at least one health condition that affects their ability to work a forty hour work week effectively. Human Resources (HR), doctors and governments have known this fact for decades.

The sickest people that I have met in the workplace are working with high powered electrical utility solar photovoltaics (PV).

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.

Avoid working in windowless environments for good health.

It must be remembered that the forty hour work week until age sixty five was designed by governments and corporations and not the medical profession.
