"The theory is that many of us rarely or never touch the earth with bare skin, and certainly not for extended periods of time. This leads to a build up of positive electrons in the body from electrical energy, electromagnetic frequencies, WI-FI and more. The earth acts as a ground, just as it does for electrical outlets, reducing the extra positive charge."

Is this asserttrue leaking through again?

Correlation is not causation. Maybe people who have enough free time to garden tend to be better off in general.

I had no idea gardeners live 14 years longer! thanks for sharing

Food for thought!
