The mortality not only for humans increases roughly exponentially with age (Gompertz law) if childhood diseases are overcome. This increase was found nicely in the Penna model of biological aging [1,2]. Recently Stauffer suggested a simpler alternative with less free parameters [3,4]. However the Gompertz law is satisfied less accurately by this model. Hence some modifications are investigated [5,6]. Our proposition considers privileges conditions for reproduction. If the late reproduction is privileged then the Gompertz law can be retrieved [6].
