If truly seen as casualties for the greater good in the medical community, there would be days set aside to honor their sacrifice.

Instead, we simply honor their memories by speaking truth.

If you, or someone you know, is injured, please report it.

**I’m still learning

**I’m still learning. ⠀

I feel as though this disclaimer should be written across my forehead. If you judged me based on where I was 20 years ago, 10 years ago, I year ago, or even 1 day ago, you might find that I’ve changed. But isn’t that what we’re supposed to do? Change. ⠀

This is why, though exhausting at times, I speak grace (as much as I can muster) to those unaware of the bigger picture at play. We are all on quite the adventurous learning journey, right? Some of us learned the hard way, through pain. And a few of us learned by watching others fall. ⠀

But grace. Grace is so needed in this hour. The incessant chanting back and forth energizes our real enemy. He laughs, while we direct negative energy towards people, forgetting that we are in a war against spiritual forces of evil (Ephesians 6). ⠀

So, today… I choose grace on this journey. Because I’m still learning, too. And reminding myself that this war is ironically not of flesh and blood (Ephesians 6:12). ⠀

Life isn’t easy. I simply hope to encourage someone as they wake… not shame them in all of the things they should have already known. We all started somewhere. My heart truly goes out to those who blindly trusted and, without TRUE informed consent, already took the “juice which shall remain nameless for purposes of not getting deleted again.”⠀

There is grace.

what’s in your water?



“Clean” ⠀
“Safe”⠀

That’s cute. 

Water bottle companies are actually bottle companies… Change my mind. 

(video)

What is REALLY “added” to the water? 

Check EWG for a rough estimate of contaminates found in your local water supply. 

In our home, we have a well and utilize @berkey_filters. Yes, I‘ve seen the reasons people choose not to use them as well. For our daughter’s dorm room, we bought a @clearly_filtered pitcher. ⠀

I don’t have the perfect answer for water filters. They are all over the map, as far as budgets go, but… I can only imagine, just about any filter is better than NO filter, when it comes to city tap water. 🙏🏻⠀

And should said city decide to cut off running water, do you have an alternate source? ⠀

where did you order your chickens?

If you know me, you know that I research, research, research before doing… just about anything anymore.

I have a soft spot for animals. Sigh. So, you can imagine I hit the books and internet when looking to order chicks! What?! I know… Since moving onto a few acres, I look at the mirror and ask, “who is this woman?” daily.

After reading over the many (many) hatcheries (local would have been best, however we were new to the area and had specific birds in mind). Here’s some of the information that helped to make our decision…

Are hatcheries humane?
https://www.theselfsufficienthomeacre.com/2013/09/are-hatcheries-humane.html (I did not/could not watch the video.)

We chose to order our chicks from…  https://thechickhatchery.com/

Chicks are hatched from NPIP Certified Flocks and carry minimum classifications of Avian Influenza Clean as well as Pullorum Typhoid Clean.  Marek’s Vaccination is available for all Chicken Breeds for a small fee.  We operate NO KILL Facilities!   All Poultry are raised HumanelyUnsold Male chicks are shipped to large Amish Family Farms.

I sleep better at night knowing my chicks came from a facility that does NOT participate in grinding, gassing, etc… baby chicks. Nor do they automatically vaccinate – you have to opt-IN, instead of opting OUT.

In our first order, we requested 15 chicks: Black Australorp, Buff Orpington, Dominique, Easter Egger, and Salmon Faverolle.  They sent us 18 very healthy chicks. All doing wonderfully!

I have found CHICKENLANDIA to be an amazing resource for chicken care.

We’re using a wonderful chick starter from Scratch & Peck feeds through Azure (have you signed up yet??).  I highly recommend fermenting the feed. (here’s why and how,  here and here) AND it has helped us avoid dealing with “pasty butt“.

Tell-a-Vision

How would you know if you were being deceived? Controlled even?
I’m not telling you that your government is controlling you, but I’m not NOT telling you that they are working to gain control. Clear as mud?
When you ask, how can people NOT see the bigger picture by now…
1 Timothy 4 —> Now the Spirit expressly states that in later times some will abandon the faith to follow deceitful spirits and the teachings of demons, influenced by the hypocrisy of liars, whose consciences are seared with a hot iron.
This is a spiritual battle and if you are not plugged into God, there is an even bigger hill to climb. I’m not simply talking about church attendees or online observers, but those in relationship with Him.
But the first step is to get our loved ones away from the See-In-In. Aka, Tell-a-Vision.
Again, I continue to speak out for the fence riders, those with ears to hear…


US 6506148 B2 – Nervous System Manipulation By Electromagnetic Fields From Monitors –  The Lens – Free & Open Patent and Scholarly Search

US6506148B2 – Nervous system manipulation by electromagnetic fields from monitors – Google Patents 

“Physiological effects have been observed in a human subject in response to stimulation of the skin with weak electromagnetic fields that are pulsed with certain frequencies near ½ Hz or 2.4 Hz, such as to excite a sensory resonance. Many computer monitors and TV tubes, when displaying pulsed images, emit pulsed electromagnetic fields of sufficient amplitudes to cause such excitation. It is therefore possible to manipulate the nervous system of a subject by pulsing images displayed on a nearby computer monitor or TV set.”

“Certain monitors can emit electromagnetic field pulses that excite a sensory resonance in a nearby subject, through image pulses that are so weak as to be subliminal. This is unfortunate since it opens a way for mischievous application of the invention, whereby people are exposed unknowingly to manipulation of their nervous systems for someone else’s purposes. Such application would be unethical and is of course not advocated. It is mentioned here in order to alert the public to the possibility of covert abuse that may occur while being online, or while watching TV, a video, or a DVD.”

https://academic.oup.com/annweh/article/54/7/789/202744

Original article – cloth masks were found to have low efficiency for blocking particles of 0.3 microns and smaller. Aerosol penetration through the various cloth masks examined in the is study were between 74 and 90%. Likewise, the filtration efficiency of fabric materials was 3% to 33%.

Original article – 1920 – analysis of cloth mask use during the 1918 pandemic examines the failure of masks to impede or stop flu transmission at that time. Concluded that the number of layers of fabric required to prevent pathogen penetration would have required a suffocating number of layers, and could not be used for that reason, as well as the problem of leakage vents around the edges of cloth masks.

https://www.nejm.org/doi/full/10.1056/NEJMp2006372

Editorial New England Journal of Medicine – “we know that wearing a mask outside health care facilities offers little, if any, protection from infection. Public health authorities define a significant exposure to Covid-19 as face-to-face contact within 6 feet with a patient with symptomatic Covid-19 that is sustained for at least a few minutes (and some say more than 10 minutes or even 20 minutes). The chance of catching Covid-19 from a passing interaction in a public space therefore is minimal. In many cases, the desire for widespread masking is a reflexive reaction to anxiety over the pandemic.”

 

SAFETY OF MASKS

During walking or other exercise

https://pubmed.ncbi.nlm.nih.gov/32590322/

Physiological Hypothesis – concern about possible burden of facemasks during physical activity on pulmonary, circulatory and immune systems, due to oxygen reduction and air trapping reducing substantial carbon dioxide exchange. As a result of hypercapnia, there may be a cardiac overload, renal overload and a shift to metabolic acidosis.

https://pubmed.ncbi.nlm.nih.gov/15340662/

Original article – patients with end stage renal disease were studied during use of N95 respirators.

Original clinical study – various respiratory pathogens were found on the outer surface of used medical masks, which could result in self-contamination. The risk was found to be higher with the longer duration of mask use.

 

38 — L Zhiqing, C Yongyun, et al. J Orthop Translat. 2018 Jun 27; 14:57-62.

https://pubmed.ncbi.nlm.nih.gov/30035033/

Original article – surgical masks were found to be a repository of bacterial contamination. The source of the bacterial was determined to be the body surface of the surgeons, rather than the operating room environment. Given that surgeons are gowned from head to food for surgery, this finding should be especially concerning for the general public who wear masks. Without the protective outfits of surgeons, the general public have even more exposed body surface to serve as a source for bacteria to collect on their masks.

https://arxiv.org/ftp/arxiv/papers/2005/2005.10720.pdf

Original article – asks assumed to be effective in obstructing forward travel of viral particles. Those positioned next to or behind a mask wearer received farther transmission of virus-laden fluid particles from masked individuals than from unmasked individuals by means of “several leakage jets, including intense backward and downwards jets that may present major hazards,” and a “potentially dangerous leakage jet of up to several metres.” All masks were thought to reduce forward airflow by 90% or more over wearing no

mask. However Schlieren imaging showed that both surgical masks and cloth masks had farther brow jets (unfiltered upward airflow past eyebrows) than not wearing any mask at all, 182mm and 203mm respectively vs none discernible with no mask. Backward unfiltered airflow was found to be strong with all masks compared to not masking.
