- You know why you need oxygen masks on airplanes?
- To breathe.
- Oxygen is intoxicating. In catastrophic situations, people panic and frantically gulp air, and suddenly there's euphoria, peace, and you resign yourself to your fate. Here's a picture. Emergency landing at 600 miles an hour. And the faces are as calm as cows in India.
- It's an interesting theory.
