[Sorry for the tangent.] Indeed, it reminded me of Jack Reacher character too. From one of the books, when another character asks Reacher why doesn't he carry spare clothes: "Slippery slope. I carry a spare shirt, pretty soon I’m carrying spare pants. Then I’d need a suitcase. Next thing I know, I’ve got a house and a car and a savings plan and I’m filling out all kinds of forms.” Thanks to my uncle, who introduced me to Reacher novels about the time I just began university in 2002. It was fun reading about 16 books (meanwhile...needless to say, I'm exactly in the opposite situation of that quote). The nice aspect about Reacher novels: you can pick up any book without regard to order, you won't miss any background context -- each book stands on its own. Certainly worth the read, if only for the vicarious experience.
