Of course I am also guilty of what I am going to say next. In the recent past we have culturally regarded thinking professions - our parents wanted doctors and lawyers, not farmers or workers - more highly than doing professions. But already the ancient Romans acknowledged that we need exercise to think clearly and stay healthy when they said “mens sana in corpore sano.” Between our sedentary professions and farming out snow shoveling, cleaning or lawn mowing, we find ourselves having to get the needed exercise elsewhere. It is quite ironic that we work long hours and don’t have time to clean or walk the dog, but then rush past dinner to catch the next exercise class or run to the gym, all the while spending precious money on all of the above.
