I stumbled across this image and it really struck a chord. I have always been fascinated by the beautiful curve of the human spine, how it bends in and out to accommodate the changing weight patterns of the human body.
See how the early caveman's back is curved forward but he (or she) probably spent a lot of time reaching and twisting for fruit in the trees, running away from predators, foraging, squatting and hunting for food to eat. They probably never lived long enough to develop health problems. As the centuries pass, the human spine becomes straighter as we learnt to handle gravity through the development of muscles in the back and front of the body. We were still hunter gatherers using our bodies in the ways that it had been designed to do by nature.
Then the Agricultural and Industrial Revolutions arrived and we began working with our hands in the fields and later working machinery. See how the spine begins to curve again, putting intense pressure on the lower back.
Finally, see the man bent over his computer with the huge curve in his back. Sadly, this is how those who work in offices spend their days and no wonder these people suffer lower back problems, upper back pain, aching shoulders and digestive problems.
We are not meant to spend up to 12 hours a day sitting at desks, our bodies are not designed that way.
It has been said that desk bound jobs are the new smoking disease.
