The video below illustrates very simply and quickly the reasons masks are generally a bad idea, especially for anyone with any chronic respiratory disease that causes reduced lung function. What it shows that within your mask the levels of oxygen are routinely below OSHA’s recommendations. While a healthy person will not suffer significantly, wearing a mask for a long period of time will certainly lead to headaches and diminished function. For a person with asthma or chronic pulmonary disease the low levels of oxygen, combined with the higher levels of CO2 (which you are rebreathing) will eventually cause serious harm.
The video comes from this link, which includes similar demonstrations.
Wearing a mask is simply not supported by the science. There is no clear evidence it stops or even slows the spread of the Wuhan virus, and it carries with it negative medical consequences.
The negative social consequences need not be discussed. They are beyond counting.
From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.
Unfortunately, that is exactly where that journey takes him.
The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.
He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.
