Important note: The Brazilian nightclub fire is a special kind of horror, and in no way am I implying that what happened was the fault of the club-goers. That whole thing is fucking heartbreaking and chilling and awful.
Here is a small, safe habit to develop that you will probably never use, but could someday make a huge, huge difference.
When you’re in a crowded place, take the 30 seconds to scope out where the emergency exits are. If you’re in a hotel, check the little diagram that shows the various ways out. Figure out, if you’re on ground level, how to open the windows. When you get on a plane, count how many rows of seats are between you and the exits, in both directions, then store that number away.
I know this sounds intense. And it is. But it’s also important.
