“More than 41,000 new coronavirus cases were recorded nationwide Monday, according to data from Johns Hopkins University. That was an increase from Sunday, but lower than Friday’s record of 45,255. World-wide, confirmed Covid-19 infections exceeded 10.3 million, with more than 505,000 deaths. The U.S. accounts for about a quarter of each figure.”
FLASHBACK: 3/13/20. “California predicts 25,500,000 cases by 5/7/20.”

Masks "interfere with many physiological and psychological aspects of task performance"
University of Maryland, Dept. of Bioengineering, Dr. Arthur Johnson
Impact of masks on human physiology.
ABSTRACT
“Respiratory protective masks are used whenever it is too costly or impractical to remove airborne contamination from the atmosphere. Respirators are used in a wide range of occupations, form the military to medicine. Respirators have been found to interfere with many physiological and psychological aspects of task performance at levels from resting to maximum exertion. Many of these limitations have been investigated in order to determine quantitatively how much performance decrement can be expected from different levels of respirator properties. The entire system, including respirator and wearer interactions, must be considered when evaluating wearer performances. This information can help respirator designers to determine trade-offs or managers to plan to compensate for reduced productivity of wearers. “Source

Mask risks "delivers less oxygen"

A person wearing any kind of mask faces breathing resistance as air filters through the device, making the wearer work harder to inhale than he would without the mask. This can have several adverse physiological effects when the mask is worn for long periods of time. Moreover, carbon dioxide that is exhaled can get trapped in the chamber of the mask the re-enter the body each time the mask user inhales. This delivers less oxygen into the body than when the person is not wearing a mask.

Mask: No Good Choices
I wear a mask where required but am sensitive to anyone who is uncomfortable with their long term use. Please read on:
Jesse Jackson, a pro-life Democrat (in 1977)
Jesse Jackson, 1977:
"Politicians argue for abortion largely because they do not want to spend the necessary money to feed, clothe and educate more people. Here arguments for in-convenience and economic savings take precedence over arguments for human value and human life. I read recently where a politician from New York was justifying abortion because they had prevented 10,000 welfare babies from being born and saved the state $15 million. In my mind serious moral questions arise when politicians are willing to pay welfare mothers between $300 to $1000 to have an abortion, but will not pay $30 for a hot school lunch program to the already born children of these same mothers."

Life is public and universal
"There are those who argue that the right to privacy is of higher order than the right to life. I do not share that view. I believe that life is not private, but rather it is public and universal. If one accepts the position that life is private, and therefore you have the right to do with it as you please, one must also accept the conclusion of that logic. That was the premise of slavery. You could not protest the existence or treatment of slaves on the plantation because that was private and therefore outside of your right to concerned.""Politicians argue for abortion largely because they do not want to spend the necessary money to feed, clothe and educate more people.

Vaccine?
If we live long enough, we all will face two choices.
Choice One: Get COVID-19 and stay truly quarantined for 14 days or until given medical clearance.
Choice Two: Receive a coronavirus vaccine as soon one is approved.
Am I wrong?

YOUNG
Public health officials look at a variety of metrics, including
new cases, percent positive test results, hospitalizations and
deaths to gauge the level of spread in an area. Covid-19 deaths haven’t
yet seen the same increases as cases, positive test results and
hospitalizations, in part because the U.S. is now identifying
more mild and moderate cases as testing expands and those cases are
now skewing younger.
