Two Types of Survivors in The Walking Dead

Been watching a lot of The Walking Dead lately and I came to realize that the survivors can actually be categorized into two groups.

First Group: The Smart and Fierce guys, in other words, the Awesome type like Rick Grimes, the guy on this walking dead shirt. 

Second Group: The Fast Runners like Glenn. He did score as hot chick, right? So it's not really that bad being a "fast food" after all! =)
