Honestly, my plan is not to let this change my life or routine. If I don't do that, then I've let someone else take control of my life.
Of course, the gym I go to is going to be closed this weekend (they're even closer to the blast site than my office), but they've already posted that they'll be open again on Monday, so I have hope that Oslo - and Norway as a whole - won't let this change their society.
I meant directly in the aftermath. Secondary attacks on groups of onlookers to the first attack are calamitous. Think a car bomb or rifle attack on first responders/EMTs. And of course now we know he had designs on additional attacks.
