The point is no one knows the whole truth about all of this. There are examples of all sorts on both sides. My case is sort of weird. I had all the symptoms for a couple weeks at the very beginning of the spread. I didn't go to the doctor for a couple weeks even though my oxygen level was around 85 all that time. I have never been one to run to doctors when sick or even take a flu shot. I always felt it was better to build my own immune system. I never get the flu and that policy seemed to work good for me.
Now back to the story. I finally called my clinic and nurse told me I needed to get to the hospital immediately. I still waited 2 days and finally went. Like I said, I had all the exact symptoms, but after several tests they said I didn't have covid, but other kind of lung virus. They gave me some pills to take and I was better in a week or so. Looking back, it was real bad, I could hardly walk and nearly passed out every time I got up or tried to do anything.
I guess the moral might be, what has worked for me all my life, finally caught up to me due to maybe age or simply the power of the viruses that exist today. Life evolves, even the harmful things. Maybe it all will get worse for humans as time goes on, with science trying to keep up with it.
Take the vaccine, wear a mask, go to the doctor. It can't hurt you to be safe and protect others in this day and age no matter what the virus or illness is.
