This brought to mind something from Bertrand Russell’s Nobel lecture (all of which is interesting, btw)

"I used, when I was younger, to take my holidays walking. I would cover twenty-five miles a day, and when the evening came I had no need of anything to keep me from boredom, since the delight of sitting amply sufficed. But modern life cannot be conducted on these physically strenuous principles. A great deal of work is sedentary, and most manual work exercises only a few specialized muscles. When crowds assemble in Trafalgar Square to cheer to the echo an announcement that the government has decided to have them killed, they would not do so if they had all walked twenty-five miles that day."
