why do we forget to do the most basic tasks we should do? なぜ基本的なやるべき課題についてわすれってしまいますか。¿por qué nos olvidamos de las tareas más básicas que deberíamos hacer?

We tend to forget sporadic tasks. Tasks that are recurrent but whose recurrence is long in time. To avoid forgetting about those tasks the best way is to set a reminder. Not just in one source, but many. So in case that it accidentally gets erased we might, with good luck be able to retrieve it from somewhere else. As we have seen many times before, we cannot rely on our companions human beings to remind us. They also forget. We can just depend on ourselves.
