The American pilgrim George Florian Walter experienced i serious life crisis in 1969. He was then a young catolic theological student. After some months pilgrimage he wrote this words in his dairy, the fifth of july 1970: 

It is to be expected that one loses the "sense of earth" and feels restless and alienated when he no longer tramps the earth with his feet but speeds over it on rubbertires or jetplanes. When he no longer feels the steepness of a hill or mountain, but just tramps a little harder on the accelerator. When he no longer receives nourishment from water flowing out of a rock, but turns a handle or pushes a button. When he no longer digs in the earth with a hoe but first experiences his food in plastic bags or on the table. When he no longer washes the dust from his clothes but throws them in a machine. When he no longer wipes real dirt from his body but scrubs invisible skin bacteria from his pale skin. When he does not feel in his hands the dampness of rainy days or the heat of a burning sun, but encloses himself in clima-controlled environment.
