Speaking only for myself, now everyone in my office has an adjustable height standing desk. It's wonderful and way better than the standing options at the prior companies I was at that you could only get if you had a documented medical issue.
I tweaked my back at the gym and spent a ~week standing at my desk. It wouldn't have been worth it to have a doctor check me out and get a special desk for just a week, so having the option was very nice.
