>>1265325>you're more likely to die being struck by lightning.>You're more likely to die in a car accident on the way to the airport.
This is such vain rhetoric, when there is a heavy thunderstorm you don't leave your house if you are afraid of lightning, if you don't want to get run over by a car you stick to the traffic lights and properly check the streets before crossing them (cars don't go faster than light), you can't avoid a terrorist attack when they happen other than by precaution.
In London the attackers just pulled out machetes as they were standing right next to civilizans and cut them down, slitting their throats while laying on the ground. In Paris the people were at a concert lined up like pigs waiting to be slaughtered, most likely dying without noticing it at first.
If you still clinge to the idea that terrorist attacks are an uncommon occurance there is no help for you, and there most likely will never be.
Still, I agree with the sentiment that you shouldn't let fear control your life. The threat is real, but that doesn't mean you should limit yourself in any way. Terrorist attacks do happen more frequently now, but not enough that you'll be caught up in one unless you go out on a Friday/Saturday night in Brussels, Paris, Berlin or London. I'd maybe avoid going to other metropolitan areas like Hamburg on weekends as well, if you really are paranoid and still want to do something. There are a lot of other things to see that terrorists don't know about. Those are the worst cities of their respective countries anyways. Go see Budapest, Rome, Vienna, Zürich, Antwerp, Münster, Ljubljana or Barcelona.
Precaution is ultimately all you can do, and avoiding those areas isn't "stupid" like some people would want you to believe. The city I live in has long had strong tensions in the Islamic community, even arresting potential ISIS soldiers at one point, and my neighbor is a salafist. I can definitely understand your fear.
