It has already been established that the mean length travelled by a neutral particle in a body containing a diffusing but not absorbing material is independant of its cross section, and consequently equal to the mean chord of the body. An elegant demonstration of this curious feature is presented and analysed thanks to Monte-Carlo simulations.
