Try one of these.

The average American spends a ridiculous amount of time Sitting, which has now been dubbed "the new smoking" because it's so bad for you. Most of this sitting occurs during the work day at various desk jobs, which is sort of excusable since after all, things do need to get done. Then more sitting happens at home, where watching other people who are also sitting is extremely popular, especially in the Trump era where the nightly news shows are the leading source of conversation for the next round of sitting at work the following day.

According to a physician writing on the Mayo Clinic website, the health hazards of sitting cannot be overstated: "They include obesity and a cluster of conditions — increased blood pressure, high blood sugar, excess body fat around the waist and abnormal cholesterol levels — that make up metabolic syndrome. Too much sitting overall and prolonged periods of sitting also seem to increase the risk of death from cardiovascular disease and cancer."

I'd say more but since I've got to sit to do it I better not. I just returned from a dental appointment (drive time 30 minutes, of course sitting), during which I sat for about 45 minutes, then drove home. I gotta go find something to do that involves standing. Likewise, you should stop looking at your computer (or your phone or laptop or whatever) and stand up, before it's too late! As my grandmother used to say (sort of), "There's plenty of time to sit at the cemetery."
