Schrodinger asked, "what is life"?

But I have a different answer. Things that are alive do not necessarily follow geodesics in spacetime (due to gravity
). For instance, birds and space shuttles do not necessarily follow geodesics (especially during take off). Lava emitted from a volcano follows a parabolic geodesic. When one dies, one assimilates with the Earth, slave to the geodesic.
Anyone else have their own theory of life?
