What about it, exactly? You can't stand 8h a day and also standing comfortably is not possible beyond 30m and that shouldn't be done more than 2-3 times a day because it's tiring, as in, it drains your energy and you can't do anything else even after work.

I do have a standing desk and I love it that I can adjust the height and wouldn't replace it with a stationary one but it's not the magical fix for the extremely destructive effects of prolonged sitting that many pretend it to be.

Standing desks are, at best, something that reduces those extremely destructive effects of sitting by something like 5%. Which doesn't matter one bit because the nature of the health destruction by sitting is that it kicks in after you go past certain time of sitting. Taking a break from sitting doesn't help much. 5-30 minutes later you're back on the chair and the cumulative negative effects from the sitting for the day are more less the same as a result.

Let's not dance around it: you should apply a non-negotiable maximum amount of sitting at the computer per day (depending on your health that is basically 3 to 5 hours) or else you'll need electro-stimulation and vibro-massage every day just to reduce the chromic tiredness by a little but still end up rapidly losing health from one point and on anyway.

From my experience unless you have some undelining conditions you can stand for most of the day. I got used to it in a few weeks time and got ridden of my lower back pain. Perhaps stand as a default and take sitting breaks as needed?

Anecdotal evidence. I've known security guards that were athletes before the job and they all said the same: "I could do various sports (or hike in the mountains) for 14-15h before needing to sleep but stand around guarding a shop for just 1h and I am more tired compared to what I was doing those 14-15h in the past".

Be grateful for your health, seriously. A lot of us aren't elves with unlimited energy.

Also I don't want to be mean but your advice is super shallow and practically ignored everything I said in my previous comment.
