Now you’ll notice how the odds of actually having to actually do the things rapidly decreased as you worked your way down the list. 

But these are things the body seems to be capable of doing. Not readily. Especially not if we are urban dwellers. 

The logical question: life is a whole lot better for most of us or some of us not having to do all or majority of the things in the list. Right ? 

But doesn’t change the fact that the body seems to thrive when you’re capable of doing those things. 

This is why we simulate exaggerated doses of activity in gyms. 

A condensed-souped up version of activity that we no longer need to get through the day. What condensed milk is to milk, training and exercise is to activity that the human body is capable of performing. Does it have all the goodness? Far from it. But it does make life sweeter.
