I have been planning to replace the cheap old chair I was using with a new comfortable leather-upholstered chair that would make my retirement, my reading and relaxation even more enjoyable. My son, who is the most Paleo person I know, entered the room and we talked about Jensen and I mentioned my plans for chair-driven comfort. He brought me up with a start, pointing out that chairs were introduced well into the Neolithic, that it is chair-based activity (driving, office jobs) that leads to back problems. He advised me to get down on the floor - as he does - to read. Rather than engaging in stretching to compensate for the abuse to my body by chairs, he advised me (with the confidence only a 21 year old can know) to get off my butt and avoid the damage in the first place. I know that when I was in the highlands of Papua New Guinea I would see the old people squatting for hours on end, in a roughly circular group, talking together. No chairs. Depictions of Paleolithic people, on the other hand, often show them sitting (when flint napping, making a spear, eating etc.). But maybe the artists was forcing them into the their modern, Western mould. Any ideas on sitting?
