Do you guys think that having this "double" (or even triple in Thomas's case) life is something that can effect us on a deeper psychological level?
Yes, and I think that's a good thing. I too am an engineer (software) and photography gets me away from computerized stuff. I also coach my daughters soccer team and that three way pull really leads to deeply split personalities.

At least 12 and 13 years olds don't permit you to get old.
