Prolonged use of masks risks .

Studies have been conducted over decades to the benefit risk assessments of use of masks. 

This studies concluded.

Prolonged use of N95 and surgical masks by healthcare professionals during COVID-19 has caused adverse effects such as headaches, rash, acne, skin breakdown, and impaired cognition in the majority of those surveyed. As a second wave of COVID-19 is expected, and in preparation for future pandemics, it is imperative to identify solutions to manage these adverse effects. Frequent breaks, improved hydration and rest, skin care, and potentially newly designed comfortable masks are recommendations for future management of adverse effects related to prolonged mask use.

The efficacy in preventing disease from from splash back from fluid or blood was determined to be a 24 percent increase in a study provided Dr with masks versus if the had not used a mask.

Tight fitting masks cause inadequate ventilation and increased levels of carbon dioxide (CO) known as hypercapnia. As CO is a known respiratory stimulant, a buildup of exhaled CO between the mask and face will cause increased lung ventilation and respiratory activity. Symptoms of hypoxemia such as chest discomfort and tachypnea are also noted in healthcare professionals with prolonged mask use. Exhaled CO builds up between the mask and face, and increased levels of CO cause confusion, impaired cognition, and disorientation

The risks of being infected with covid 19 is DEATH. 

You Are such a fucking waste of time.

You needed to be told this?

You needed decades if study..that's a lie by the way. It's common sense that you don't breath your own hot air for hours. It will eventually lead to health problems

Yes it needs to be studied and was,  because masks are costly neatly 10 million was thrown away in operat88ng rooms per year.

English and others reasoned if these are completely useless and causing adverse reactions then not needed and  should not paid for alot of science came from actual studies. They once called a method of research the scientific method....

But what would care all science us fake

what got me on this path to find research

was raiders22.

He isn't running his mouth cause he wants likes or worse recognition...

it's always a validated opinion that has been research and can be a considered at times dissenting opinion backed by doctor level fellowships in what ever academic discipline he is engaged with.

If you told me it was going to be hot I would trust that I need to check the thermometer before turning on an air conditioner. Chic.

I believe in math... everything else is an adaption of vibrations within frequencies of notes that created the universe. But it's the math that describes the strings of his guitar.

Math describes a violin to a Stradivarius standards.

How those strings in theory is played 

Is how the piper plays his tune.

And as lovely it sounds I ain't really up for a square dance And a hoe  down as you try to pick a fiddle....

I suppose that last post could be considered a manifestation of seeing an amazing violinists on Sunday today...

recirculating your own CO2 is not healthy....no matter what way you try to spin it

and its CO2 not CO.....

Co2 is inert co is deadly 

I know math.... if you do not get enough oxygen,  then you admit co carbon monoxide. 

Because you measure food in calories, calories are thermal dynamic of energy released while oxidizing and element.

Hence with less oxygen your thermodynamic burning system your body will create co which bonds as oxygen to a red blood cell

Than co2 which is released.

Science is a vulgar adaptation of theoretical math.

Opinions are not facts but based on facts how interpreters suggest that fact means is an opinion.

Math easy  2 plus 2 is 4.... And all the torture pressure and belief of relevancy will not make the answer 5 no matter how you suggest the 0 through 9 figure counting system is described. 

Eh? You want to explain that clearer 

Fine say all computer science is a on or b off.

0 or 1. Bases of how you look at your web enabled device. 

Easy if you inverse what on or off within cyber space than you can charge to utilize the 0 or 1 concept if it's bothers you than pay to make that 0 if you want it k. Pay for 1. If I knew what you wanted you lay either way.....

Again not bill gates and the vulgarity of computer science just the idiot that can state this will or will not work based on mathematical design.

And none can say what doing it only hunt for a clue.

Activation of the population emerges to steal your self again i am aware of the interest. 

Et came here.  You were dropped off , but if humanity can make its own ride no one going to pick this humanity up and drop it off anywhere home eh spock.... where you going.? The grave. 

Sooner later... it's all now someday
