> One day I was doing work on my laptop on a couch because hitting 30 apparently means that sleeping slightly incorrectly results in debilitating back pain.

A factor in my debilitating back pain for me (was 31 and fit; now 37; getting better) was coping with back pain by moving to unergonomic positions like the couch/bed, which led to different and thus compounding compensations, and thus more complex recovery.

Now if my back is painful in a position, I take it as a signal to move my body, not find another static position that doesn't cause pain.

That can sometimes be difficult to do, with job/family requirements though.

Sorry to derail the post, but I hope this helps someone avoid my issue.
