Image this. You've got a nice, active lifestyle going, and you set about your day without providing a second thought to whether your body is operating as it should be-- due to the fact that it is. Not a tough thing to think about, really, since that's exactly what we do-- one could argue that this is all we do-- every day. We set about our lives, working and consuming and communicating and such, without needing to fret about how well parts of our body are operating or whether they might be in need of maintenance or care. This is absolutely not uncommon, considered that the majority of people don't have to fret about such things.We pay extremely
little attention to our body and its prominent parts due to the fact that it works so perfectly the majority of the time. Why indeed pay any mind to something that practically takes care of itself? If we were to take a closer look, though, we might find that our bodies-- especially our joints-- are engineering marvels, with the lots of functions and movements so exactly collaborated as to make any maker envious.
