In this talk we review the concept of "universality" in the development
of very high energy cosmic rays showers. The main result
is that the distributions of photons and electrons in a shower
have shapes that are essentially determined by the
the stage of shower development (the shower age)
independently from the energy and identity of the primary particle.
