I'm coming up on my 5-year standing anniversary.

One thing I've noticed that the video doesn't mention is what it's like to work at a sitting desk after having exclusively stood so long.

It sucks.

My hip flexors aren't used to sitting for more than short intervals, which means I can't work at a sitting desk for a whole day without having hip pain.

This was an issue last year when I did some consulting at a company where they didn't have any standing desks available. (At some companies I've actually started the standing desk trend, but this Major US Cable Company was having none of it).
