If you think about it, nearly every new invention over the past 30-40 years has been for the sole purpose of making us more "efficient", thus reducing the amount of physical labor we have to put into accomplishing everyday tasks.
My momm's side of the familiy were farmers. Living in the country getting up at the crack of dawn working hard labor until sun set. That generation all lived well into their 90s My dad's side of the family were all city dwellers. Relying on machines to do wrk for them eating greasy, starchy food. They almost all died in their late 60s! America need to incorporate moore physical labor into everyday life. Driving is boreing. I'd rather ride. Unless there is a hurricane coming!!
