Communing with nature

Life has its many stresses and some say too much stress can shorten one's life span and even maybe cause cancer and other horrible ailments... i was very interested to hear that certain experts in health and well being are now saying that the key to a long happy life and freedom from illness is to commune with nature for at least 30 minutes a day....i deeply ponder this and wonder if i spend 30 minutes a day cutting down trees and shooting possums with my grandfathers rifle, could that be considered communing with nature and is it so wrong to want to eat nature whilst your doing it??...now that's food for thought...Tartly Roud
