Yeah, I*mm going to have to agree with most others here. That it's the point of having fresh meat. But then it'd have to be something that would tell them to go for the fresh meat, as I find it hard to believe they have any way of tasting anything. What with their brains not being in tip top shape and stuff. They can't really feel pain either. Therefore it must be assumed that they are simply drawn to it.
Some might say that it's a bit more of a vampire-esk thing they've got going with brains. As we know, it's a common conception that zombies enjoy eating brain. And some might suggest that they need these brains to continue. But that I strongly doubt as they are running around for greater amounts of time before they eat any brain. But while we're at the brains part. It might be that that's attracting them. The brain somehow attracts them. Perhaps a smell, or something. Because surely they can smell? Right?
And as for the point of passing on the infection, I'm not sure I'd place my money on that. Because zombies doesn't seem to even recognize other zombies. They're allways ignoring and in worst case pushing each other away. And if this was a point of passing the infection on, I'd think that they would at least recognize those with the infection. Just my thoughts on the matter.
