Why Connecting to Earth is So Important
Everything in your life is stealing electrons from you.
If you are disconnected from the earth (because you're always wearing rubber or plastic soles), you can never discharge the static electricity accumulating in you (read - inflammation).
The Earth is rich in electrons because there's always lightining somewhere at the equator - those electrons get re-distributed around the sphere immediately.
There's a reason why we have eccrine glands on our feet. We are designed to connect to the ground with our bare feet, to gather electrons to stay healthy.
