Am I Too Selfish?

When I first watched Grey's Anatomy, I didn't really like it. But now, due to the lack of things to do and things to watch, I have started to watch the series.

Day before yesterday, they aired an episode where there was a bomb scare in the hospital, in the operation theater, to be more specific. The bomb squad was called and everyone in that particular wing of the hospital was asked to evacuate. Most people did. However, there was a brain surgery taking place in another operation theater next to the one with the bomb and the surgeon there refused to leave, saying that if he left, his patient would die. That got me thinking, what would I do in such a situation? Would I be willing to sacrifice myself for the life of a stranger's? Would you?

I don't think I am selfless enough, at least for now. If I see people fighting, I go the opposite direction. Would I run in a burning house to save a kid? I don't think I would. Maybe I am just selfish. Obviously, I would hope that others would help me when I am in need. Why can't I do the same when others are in need?
