« In subjects without particular problems, there is a direct correlation between the number of walking steps taken each day and the feeling of energy and good humour. About ten minutes of brisk walking is enough to elevate our well-being, and the effect lasts about ninety minutes.

Look at these metallurgical landscapes, the atmosphere of corrupt cities (the coloured lungs of Louvre), the air and their birds stuffed with insecticides, fish poisoned to the bottom of the oceans by nuclear waste, everywhere the lifting of carcinogens, the mind-blowing speed, the infernal tintamarre, the great panic of nerves, hearts, souls, chain, chain I tell you... such is industrial life, atomic life. The great crime of modern man! yes this is just a cry: Fire! To the madman! To the murderer! Another of my favorite authors, Louis-René Des Forêts, wrote: "The overabundance has nothing to do with fertility. Nothing to add. »
