As in his other anthropomorphic works, Martínez sheds light on the fragility of the body, which is also accentuated by his choice of materials: latex, for instance, or even edible elements. By mechanizing and protracting a process as automatic and imperceptible as breath, the artist emphasizes both the role of air as the basis of life and its biological and economic costs.
