I doubt hunter-gatherers spent 8 hours a day lifting heavy objects.  But I  
do get your point.  Humanity has invented all sorts of labor-saving  
devices, making jobs easier and himself weaker in the process.   No  
argument there.  My point was just that there are opportunities for people  
to use and move their bodies, even strenuously so if they desire to, but  
it may require a little imagination to come up with them outside of things  
people perceive as "exercise".
