To be a modern person in 2012, you are often required to have some electronics in your life. And I do. I try to put that phone down, put the computer away, and get out there and hike in the woods; feel it in my feet, feel it in my hands; get out in the garden and feel the soil under my fingers, my fingertips and my fingernails.
