The titel of the exhibition by Uwe Ochsler STOFFWECHSEL- STOFF implies the term of Process. Matter changes in the process of development into another, constantly. The individual experiences an end to this development, like Mrs. Lohmann elaborated from a natural science point of view. The substances from which the body developed keep staying within this matter exchange process though. About the special case of the process of mobilisation of a machine Mr. Hochstein gave information.
Oliver Ross distanced himself as a living human being and artist from unproven consumerism of the terms and means of presen- ting and put the artistic view in opposite of the scientific view. By that he made the approach of the artistic experience a subject (live to see), by differentiating from the distanced term of the scientiest, Mrs. Lohmann, who termed the metabolism as power station of life. This enduring  of the nature on one's own body as an appearance of experience, as Oliver Ross said, belong to the process of fermentation, as Sigrid Puntigam mentioned in her arguments, in which she followed the history of the term amongst others, a process of fermentation that is much more than a wine grower can handle or a politican can steer, but rather one by which the person, the individual completely is affected in their endeavor (Hajo Schiff and Ulla Lohmann) for development (Joseph Beuys).

Hajo Schiff confronted the by Sigrid Puntigam quotated metaphor of the rose after Gottfried Keller - as a model for body, completness - with the artificial cold animal that a machine is, whose danger is the self-referentiality, hence ambition without devotion. (Whilst I write this, an ambulance is driving by outside.)

The movement as possibility of self recognition, the gaining of a relation (Oliver Ross) to one self, which brings about attitudes, that are no longer matter (Hajo Schiff) ), recognitions of metaphysical connections, the recognition of things very different , the 'world' also of the other human being, asHajo Schiff noted, the ambition for refinement, the improvement of the own kind beyond one's own death (Ulla Lohmann) has been motive and aim of such processes of fermentation forever. Such processes do not go along with comfort and cosyness, like Mr.Hochstein. describes it. The cunning of the machine handling human (Jean-F. Lyotard*) to be stronger than the strongest with comfort and cosyness comes from - according to Lyotard - the wish for getting over powerlessness no matter what the cost. As understandable as it is in the face of the process, as much does it not lead to the changing process, the burning of habits in order to gain refinement.
The metabolism in the closed system of the otto-motor, independent from any cardinal points (Michael Hochstein) as freewheeling powerplant so-to-say, is at the disposal for the open system Human Being. The refinement of matter to spirit (Hajo Schiff) that is no longer matter,  does not find an analogon in the exchange of petrol into exhaust, possibly though from petrol and air into movement, if this movement helps unveil illusions (Hajo Schiff).
