Be alert but don't be afraid

We are all very aware of the terrorists attacks that took place in Paris last week. The news crossed the whole world and everybody still feels upset about it. After something like this happens people start feeling unsafe and being scared that they might be attacked next. Consequently, they enter a state of paranoia which I think is not healthy at all. For example, I have received multiple text messages in the past week "warning" people against travelling to big cities because of the threat of another bombing. To be honest, I believe all of them are totally false. It is pretty unlikely for an attack to happen so directly after another, since security has been extremely reinforced and people are alert. We shouldn't put an end to our plans or start acting differently out of fear because if we do, we would be giving the terrorists what they want. To summarise, their strenght partly consists in everybody being scared of them.
