So, how long do you want to stay dead?

I should rephrase that to be, how long do you want to stay UNdead?  I am fairly certain that filling oneself with preservative-filed "foods" (BARF) will keep one preserved well past the grave.  Eating whole foods, foods as close as possible to it's original form, sans preservatives will allow you to rot peacefully away post-mortem.

When the ZA springs forth (as observed, probably at the airport), eventually we may all come to an inevitable end as the walking dead.  We have a choice, to stay undead for a long long time, to get shot in the head, or to rot fairly quickly and have the whole thing over with.  Eating a diet of BARF will not only speed the ZA along, but will undoubtedly prolong one's tenure as a shuffling flesh-eater, and I really would not recommend it.

Now for the only warning about eating clean, healthy foods: People who eat clean and healthy foods tend to not be placated easily; they tend to be uppity and speak out against things that are obviously wrong, stupid, or impractical.  If you eat the clean foods, especially spicy foods, you may be more likely to become a rage zombie if infected.  However, infection is unlikely as you will be able to outrun and out think the shufflers that eat BARF.

Have a healthy life and a rotten death. :)
