31 years old. I've been using stand up desk for more than a year and half now after succumbing to a lower back pain and having to sleep on the floor for more than a month to get at least some sleep during the night. It worked for me. For the past 3 years I continued working a lot of hours at a computer (my side project, my main work, and sometimes some consulting work for clients). I don't stand 100% all the time though. It is more like, somedays I sit more, somedays I stand more. I believe the key here is listening to your body and ability to easily change the position accordingly (sometimes I feel like standing, other times like sitting).
