While a fun quiz, I think I'd really have a lot of possible roles post SHTF.
Doctor - I'm not quite EMT level yet, but constantly learning more, and learning a lot of veterinary med with all of our animals. Due to my wife's maladies and my daughter's, I've learned a lot about different medications, and I'm studying up on herbal and alternative medicine too (though I'll stick with modern where I can!).
Farmer - Just getting into this, but luckily, this area is great for it. (includes other redneck skills such as animal keeping and food perservation)
Trader - Once things settle down some, post SHTF, I'd be looking to trade excess produced goods for other, likely looted items from cities, from travelers.
Sentry - I'm not in great shape (though that would change post SHTF), but I am a pretty decent shot with a pistol or rifle. I'm no sniper, but I'm going to hit what I aim at, and put it down.
Mechanic - I'm pretty decent at minor electrician, plumbing, carpentry, and masonry jobs, as well as just fixing things in general. While older cars are easier, I can troubleshoot and fix some basic auto issues as well (just don't look to me to replace a tranny or anything). I'm pretty good at figuring out how things work, and coming up with a solution to get them working again.
In each of these, there's going to be someone in my group that is likely better at any particular ONE of these things, but being able to help in all of them, is a pretty good asset I think. At least when not being the Dictator....lol.
