Sucks to say, but it is almost certainly the case that you need fewer 6 hour stints of work. Go for a walk. Think. Do some physical labor. All things are likely a good idea to help with aching bodies.
I'm not short, so I definitely appreciate having a desk where my monitors let me hold my head higher. I just don't know how much the extra monitor space really helps me. Especially tough as any change in setup usually gives me an initial boost.
I find the VR ideas interesting, but I am rather turned off from the ideas that were shown in the advertising for this one. Games and maybe in flight use seem nice. Games I already have with the psvr2. In flight... I just don't fly that often. Everything else, my home is way too chaotic for some of it, maybe?
At any rate, annoyed with myself for seeming like I'm attacking your idea here. That was rude of me. I'm genuinely curious on what got people to pick this up over other VR solutions. I think VR has gotten way better than folks realize and that most people have written it off.
