Sepehr-R (Serpent)

I feel like in order for Day Z to really be a game about Survival, there needs to be a tolerance and will to live system in the game. For example, a character will become more tolerant to cold, pain hunger, etc. if he or she is exposed to it for some days and has survived. Also, a will to live system would be nice, for example, a character with very little will to live, (due to not finding gear or constantly getting close to death or starving, or even seeing a friend die) will get hungry, tired, etc. faster but a character who has a very high will to live (lets say from killing lots of zombies, eating a good meal or finding high tier gear) will receive a bonus to his or her stats.
