Grey's Anatomy, Season 2

Meredith:
[voiceover] In hospitals they say you know. You know when you're going to die. Some doctors say it's a look patients get in their eyes. Some say there's a scent, a smell of death. Some say there's just some kind of sixth sense, when the great beyond is heading for you, you feel it coming. Whatever it is, it's creepy. Because if you know, what do you do about it? Forget about the fact that you're scared out of your mind. If you knew this was your last day on earth, how would you want to spend it?
