Watching while someone is sick is different, I think, and certainly more exciting, what with the prospect of them suddenly vomiting on the floor and all.

But if they're not sick, well, I just don't see the interest. Not only is it boring to the extreme, people aren't particularly attractive while they sleep. Or at least I'm not. I snore and drool and mutter incoherently. Heck, cats are totally adorable when they sleep, and I can't even watch them for very long.
