Depends on how zombie is defined. Some resurrections are a good thing, find a pertinent thread and ask further question if needed. No need to start a million threads if a few will do. Keeps it simple in that search y'all sometimes complain about.
My feelings are that you are just embarrassed that you didn't look or that you haven't taken something into context.
A few threads should have been left in the desert for the buzzards but this question has come up more than a few times in the 12 years I've been here, and just as quickly died.
And yes, the best warning system you have are these two items separated by your nose. Use them well, like you do on the road.
