Hmmmmm, me... Well, engineer or mechanic is likely. I love making and fixing things.
Soldier or scout is also possible - I like weapons, have a bit of a hero complex/daydream, I'm quite patient, and I have good night vision - and I might not have thrown my back out if it weren't for the crazy heavy textbooks that U.S. schools use! I'm pretty fir, and respond well to organized training. Oh, and I'm clearly part cat. All my friends agree.
The other likely possibility is seafarer, as crew aboard a Viking liner. And probably a mechanic there too.
