When you're flying with small children, why do they tell you to put on your oxygen mask first in an emergency?
ANSWER: Because the children might not be able to take care of themselves - - - and if you don't take care of yourself first, you might not be able to either. This applies in a LOT of situations. So, especially if you're going to help others, it's your duty to take care of yourself first. --L. Reichard White, 1998
