How to test and use an earthing or grounding mat plus my health experience from using one

How to test and use a grounding mat for health benefits and what has been my experience.
I watched the video after I uploaded it and the wiring is not as clearly explained as it should have been.
On the multimeter, there is a black ground lead plugged into COM or the ground. The probe end of the black lead from the multimeter has attached to it a green wire with an alligator clip. One end of the green wire is attached to the probe end of the black ground lead and the other end of the green wire is attached to a machine screw that was inserted into the ground hole of the electric plug receptacle. By doing this I grounded the multimeter in the same way the mat is grounded.
The red lead on the multimeter is the positive lead and is held in the hand. The white wire is attached to the grounding mat with a metal snap and has the other end inserted into an electrical receptacle in the ground hole. All of the receptacles were tested with the receptacle tester. When the mat is grounded and the multimeter is grounded and the red positive lead is held in one hand and the other hand touches the mat the voltage reading which is the amount of voltage in my body declines dramatically. When I test the mat in my bed away from electronics the reading will go to zero or close to it.

Here is a link to the health study on grounding and earthing published in the National Institute of Health

Here is a link to my review video playlist of the stuff I have reviewed over the years.

A few extraordinary people who appreciate my over 860 weekly helpful videos have saved the Amazon link I will provide below. This is my link to my Amazon page where you can see stuff I have bought and liked a lot over the years. You do not have to buy anything from the page, because just by using my link to enter Amazon anything you buy on Amazon will help me out at no cost to you. In addition, If you save and bookmark the link you can use it to go to Amazon in the future. A few nice people have done that and it helps my channel out a lot. Didn’t you want to buy an island or jet aircraft on Amazon today? Or at least see the stuff I have bought and liked on Amazon over the years?

I want to thank you guys again for showing up and watching me trying to have a little fun or show you something that might help you out. I made YouTube videos for fun years before they paid a penny and I will continue to do so as long as it is fun and you guys keep showing up.
