I thought I'd expand a little for anyone who thinks, "We said that already!" Sometimes hearing a thing said a different way makes clear something an expert wouldn't have questioned in the first place. I read qi was breath and in "everything". I took that to mean "everything (living)" with living being provided by the context. In the definition I quote it is clear that I misunderstood and it really is everything (living, dead, photons, everything). Then again maybe I'm still getting it wrong. Also I read about the romanization and I figure that's all in the past. Another quote shows me there are many current other English spelling for qi. And so on.
