As I've been slowly recovering from back injury/surgery over the past few years, I've been unable to sit for long periods of time. In order to be able to write software at all I've had to construct a laying down desk where I look up through a glass table at the monitor.

I wonder, does this improve my odds wrt to the article? Or rather, is it that 6+ hours of waking inactivity increases the likelihood of premature death? (either sitting or laying down)
