&gt; Working standing up has similar effects as &#x27;pacing around&#x27;, when needing to think about something intently, gripped by thought enough that you&#x27;re compelled to move around a little... I can&#x27;t imagine being deep in thought and just sitting still.<p>It&#x27;s really hard.  I have had to get used to it, though, because I have yet to work in a place with enough space where I can do that.
