I like to use words like "thus", "hence", and "therefore" a lot -- but this is because, as a mathematician, I picked up a style of writing that has been deeply influenced by the mathematics I learned.

For that matter, the first day I was in Great Britain, I noticed that the other Americans I met had British accents, and I noticed in the few hours talking with them, I was already picking up on the accent myself.

It's only natural to pick up the language and idioms of the cultures you happen to be immersed in!

(And this applies to Law and Engineering as much as anything else, too.)
