5.2.4 Reversibility

<Cesar>We learn and forget. We build and destroy.</Cesar>
<Aissa>Reversibility applies at different levels in the life cycle of the object, about
the materials first of all : how a raw material is transformed, used to finally return
to its biological milieu the earth or to be mechanically transformed again for an
other use as objects. A system design with ecology in mind.
Than you have a current reversible usage : a table that can become a bench, a
chair or something else, it contains a variety of uses by its simplicity. To make this
possible you need to make sure that the technique you use to assemble the piece
is reversible : a nail isn’t made to be taken off, screw are supposed to be reversible
but it is not very much the case.</Aissa>
