So, to address a problem we have around here sometimes, I would like to clarify. Metaphor notes: Airplanes often have oxygen distribution systems for use in the event of depressurization. If you do not get your mask on, you pass out. If you pass out and do not get a mask on within a bit, you can die. Problem: People tend to try to put masks on children, but then the children don't know to put the mask on the adult, or can't. There is a general policy that people are usually aware of: "Please secure your own mask before helping others." This resolves the issue. A kid who passes out from lack of oxygen will be fine if the adult puts the mask on ten seconds later. But after talking to people around here more, I'd like to clarify: Do not remove your own mask to assist others. It won't help.
