So, how long do you all think Lee would have lived had he not been held back by Clementine? He was able to fight his way through a walker hoard without even getting injured....unless you fail that part, then he dies lol. But the point is he seems much more capable than the average person to survive the zombie apocalypse.
You can even beat Molly in a fight, and look at how good she is at surviving....
So, how long do you all think Lee would have survived had he not had Clementine to protect? I personally think he would have survived a long time, years, maybe his whole life.
