Well, there's this, too: your body is matter, and as the link in the GUardian points out, decomposes when entropy takes over. However, while you have and operate it there are a lot of choices about what it will do for you on any given day, where it will plant its feet, what noises will come out of it at either end, what it will grip or swing or hit or lift or stroke or pat.

All of these decisions essentially come primarily from you.

But on a much larger and much longer scale, the answer is "organizes it".

Dunno what to tell you about empirical testable proof, PP.
