Quote

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, absolutely free from all worldy engagements. You may safely say, A penny for your thoughts, or a thousand pounds. When sometimes I am reminded that the mechanics and shopkeepers 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, Walking
