my question is in the title, i want to know what kind of body modifications or body adaptations needed or look like for human to be able to sit in prolonged time without affecting their health. Since as far as i know human body is not effective in sitting in a prolonged times or stay still in prolonged times which is unhealthy to them and can affect human posture.
This excluding any tools adaptations, i want to know the body adaptations, and yeah i know there exist some chair design that try to thwart this problem, or maybe in the future portable pc or phone maybe strong enough or has enough feature for ppl to work while doing active activity rather than today common desk job, so who know would such body modification would become a reality or not, beside human are generally lazy after all.
And to be clear, i mean sitting in general not really stay/stand still, which also include other sitting posture if possible, excluding traditional japanese formal sitting, which i dont think it should be considered sitting posture to me, since it feel more like a kneel/kowtow/prostrate, which more affecting the knee rather than the rear, but feel free to correct me or add it too if want to, it not hurt to know. but just the common sitting in chair is acceptable too.
And if possible they still can walk or do activity if want to, even with that modification, just in case ppl will suggest something like merge them with sitting chair or change the human posture to permanently in sitting position or posture and only can sit while the chair bot do all the activity for them.
here a gif from cyanide and happines....just because.
feel free to correct my grammar or put appropriate tag to my question.
