Having researched this way back at the start, lets start by saying this, Covid is a form of flu. It can for some be serious but, those people generally have other underlying health concerns which have weakened their immune systems. As somebody mentioned already the authorities have already stated the PCR test are not good reliable test. What is worse is that the inventor of the PCR test came out and stated his test was not a reliable test. Strangely enough he died a short time later and some say under questionable circumstances. I can’t verify that but, I have little problem accepting it as true.
Another point is that if you are of reasonable health and young enough then even if you get symptoms they will be mild to moderate. At worst it is said to be like the worst flu bout you ever had. But even with that survivability is still running at 97% or better. That comes from the many good doctors that are not playing along with the political side of this whole mess.
A little personal info for you to think about. I am 65, my wife is 66. In 2016 I had a triple bypass, I am slightly over weight. I work some long hours at times. I do not wear a mask unless I am absolutely forced to. I meet with people in public settings day in and day on my job. I have not gotten the Covid, a cold, or flu since the start of this mess. My wife went through chemo for cancer a year after my surgery. She had chemo, surgery and like me works with the public but, in her case mostly kids who are more likely to spread it than adults. Now she wears a mask at work as it is required only then. We do not wear mask at home so either one of us could pass it to the other. That has not happened.
What I am saying is my wife and I are candidates of getting it and then having a severe bout with it yet neither of us have done much more than we did before 2019 came along. That alone tells me that while it may exists and even that is questionable if what is said about never having been isolated is true, it is not a dangerous disease like it is being portrayed to be. Likewise the only true testing that seems to confirm anything is the antibody testing and all that confirms is you have had and your body can now beat it if you immune system is strong enough to do so.
So then that leads to how to keep your immune system strong. It is said by a number of nutritionist that 90% of your immune system starts in your gut. If you have a good functioning gut where your food is broken down well and the many nutrients are correctly absorbed you immune system will function properly. So the best way to do that is in your diet. These days if you eat processed foods, that is stuff that comes in cans or boxes as opposed to buying raw vegetables, fresh meats, etc and cook your own meals at home your digestive system is likely compromised because of all the sugar and chemicals that are added. In short you are in a toxic state and your immune system’s first line of defense is not working properly. You are not getting the necessary nutrients to keep it strong.
That being said you can boost it two ways, change your diet if you need to. First of those is drop the sugar. Sugar is known to cause inflammation through your system. Lower the sugar intake and you lower the inflammation problems. Next is eating fresh foods, cooked at home where you know exactly what is in them will keep harmful chemicals out. After that you can also boost your immune system with supplements. A simple multi vitamin will do wonders for you if you eat well enough already. Just make sure it has vitamins, C, D3, K, as well as both A and B or B complex. It should also have in it minerals and the ones best for the immunes system are zinc, magnesium, and selenium. If your multi vitamin is lacking any of those you can get them individually and take them with the vitamins.
This is all that my wife and I do. We cook 99% at home, we take vitamins and minerals. Since we are both candidates for one getting covid due to age and health issues but have not gotten it given the many daily chances to do so should let you know that your fears are not of the disease but come from all the news that is being pushed via the media and political posturing of government officials.
Now lastly and the most important thing of all is that my situation is not your situation. That goes for everyone. We all have differing bodies, genetics, and so on. So the best course of actions is take this to the eternal physician in prayer. Seek from God wisdom and guidance and He will give it to you to take the appropriate steps as they pertain to you. It may come though the hands and minds of humans but He will provide it. God is ever faithful. I can attest to that in my own life, in the life of family members and friends that I have known for years. Trust in Jesus. He wants to take care of you. He wants to let you know what you need to know. You just have to given him the chance.
I can tell you from experience He will lead you through this, He will calm your fears, and He will give you peace. I say all of that from personal experiences some pretty dire. He has never failed me ever. I hope and pray that you can seek and find strength, peace, and wisdom.
