Even when communing with nature we depend on technology for help - but then，so did Thoreau （梭羅） at Walden Pond （瓦爾登湖）.
   Walking in the same woods yesterday，I let myself wander at random，communing with nature.
   I took in beautiful scenery near and far thanks to my progressive-lens eyeglasses.Occasionally I'd pull out my smartphone to take pictures on anything interesting.I recorded an inner monologue with a background of all sounds of the forest.At times，I consulted my smart watch to check on my heartbeat，mileage and calorie burn.Eventually I realized I was quite lost.Not a problem of course.Online maps came to my rescue.
   But something bothered me.In what I'd intended as a nature experience，here I was using very high technology to help myself out.This insight triggered a reconsideration of everything that happened during my "nature walk，" which had been technologically enhanced every step of the way.I'd been functioning as a man-machine combination：a cyborg.
   What would the true naturalist Thoreau think of that？My first thought was that he'd be shocked.But later I did some research.Thoreau enjoyed what his spyglass discovered，like this eagle from his journal：
   Lying on the ground with my glass，I could watch him very easily …till I almost lost him in the clouds ...I think I have got the worth of my glass now that it has revealed to me the white-headed eagle.
   Famously，Thoreau always set out equipped with a walking stick，which he used not only for support but also to take measurements of water and snow levels.His hat was also a tool，which he called his "botany-box." And he was prepared even with needles and thread，so when coming out of the woods，he was "the best dressed." Clearly，Thoreau was a bit of a cyborg himself.
   Thinking more deeply，I realized we've come a long way from our hunter-gatherer ancestors，who walked from necessity and relied on nature's gift.Cyborgs are us.
