I have recently found an interesting documentary called Earthing.
I found that they have presented the science behind earthing and grounding which to me it is rather fascinating.
Below is the YouTube link to the documentary. I hope you benefit from watching it and we may or may not need to spend on the gadget. But certainly we can adapt the knowledge to benefit our life and can help healing ourselves in both physical way and spiritual way.

Please note, I do not get any money from mentioning this in my blog nor knowing them personally.
