Heya Dee,
If you don't mind my advice, me and my brother were pretty much the same as the sons you speak of. I was high strung, whereas my brother was laid back. What helped us both was organized sports. It kept us focused, we had teammates to rely on, and the workout regime can be just what you need to take your mind off the mindless. The sport they choose should be one they want though, soccer, karate, whatever floats their boat.
What I wrote sounds like a typical male view, but really it's true. You learn a lot from working with a team, focusing on one thing, and doing something you enjoy.
Oh, and yea I went to Oxford, to a couple pubs with my dad when I was 9 (unfortunately they didn't let me drink :oP).
England in general was a beautiful place, plush green fields all over! Cornwall, aha! You're nicking at my memory with these, my parents were travelers, so I've seen above and beyond where we lived. I also remember the subways had problems with scorpions for a little bit there (always looked for them!!! never found any...), they ever fix that?
