**Resumo: **I am going to show, that the blow-ups of solutions, that usually are treated as *something "very bad"*, can in fact describe some *self-organization* phenomena, "positive" (like healing) or "negative" (like society polarization) - [1, 2]. Mathematically it is the theory of integro-differential equations (*kinetic equations*) that is applied to processes in Social Sciences (opinion formation) - [6], Economics ("lemons and cherries" theory) - [7], Biology (DNA denaturation) - [4], Medicine (tendon healing process) - [5] and the redistribution in a lift - [3].
