" What is work for?" 
If it is to get the job done then indeed get a chain saw. If however it is to connect with nature ; to know the tree and the rhythms it asks of our bodies. then lets use our hands our arms our feet our lungs.
        "You work that you may keep pace with the earth and the soul of the earth.
           For to be idle is to become a stranger to the seasons,----
           When you work you are a flute through whose heart the whispering of the hours turns to music"
