From last year, but relevant: the impact of our new working-from-home reality on our posture and the health of our backs:

“More recently, as the coronavirus continues to keep us mostly indoors, working in improvised offices where ergonomically unsound ironing boards, coffee tables, and laps pinch-hit as desks, our sloppy ways of sitting could be taking a toll. Parked in front of a computer, we tend to tuck under our tailbones, candy-cane our spines, scrunch up our shoulders, and crane our necks forward like wilted sunflowers. According to many experts, for every inch that the head lists off kilter, the force impinging on the neck and the back increases by ten pounds. A survey among seven hundred and seventy-eight software workers in lockdown last spring found that shoulder, elbow, and wrist pain had doubled. Bad posture has been blamed for indigestion, constipation, high blood pressure, cracked teeth, infrequent orgasms, negative thoughts, and difficulty performing arithmetic calculations; somewhere, someone has probably implicated it in the Presidential-election results.”
