Walking

I think that I cannot preserve my health and spirits unless I spend four hours a day at least — and it is commonly more than that — sauntering through the woods and over the hills and fields absoutely free from all wordly engagements. You may safely say a penny for your thoughts, or a thousand pounds. When sometimes I am reminded that the mechanics and shop-keepers stay in their shops not only all the forenoon, but all the afternoon too, sitting with crossed legs, so many of them — as if the legs were made to sit upon, and not to stand or walk upon — I think that they deserve some credit for not having all committed suicide long ago.

Henry David Thoreau - 1862
