The agency says that in heavily crowded areas, people should "try to walk around crowds rather than through them" and that attendees ought to "stay on your feet – do not sit down or bend down to pick something up."
In other words, make sure your shoelaces are tied before coming to see Pope Francis.
If you do fall or bend down, though, PEMA adds that you should "get back up on your feet as quickly as possible."
It isn't offensive advice, just...duh?
