I'm not one to be barefoot all the time, but I have always enjoyed the feeling of 'Mother Earth' under my feet ... the different textures - sand, dirt, grass, concrete walkways - even mud squishing between my toes during and after a nice warm rain!
Dr. Mercola thinks it's a good thing as well. I'm sure that staying 'grounded' as it is called in Dr. Mercola's article, is helpful.

To find out more about your body-onics, as I call it, see one of my favorite websites: www.altwaters.com ... I wear a medallion daily that helps absorb all of that 'chaotic' electric that surrounds me. You can purchase one of these on the Altwaters website, and other products for ultimate health and wellness. Learn how to be healthy, from the inside out!
Along with staying 'grounded', I'm an advocate of drinking plenty of good water, daily.
