Good luck to to you and the family, it's going to be a very special New Year for you all! Our reasons are pretty much summed up by mrs BJ, Why Not?? We don't have kids and have none planned, so apart from our immediate family (who are all wondering why we are still in the UK!) there really isn't a good enough reason for us to stay on the corporate ladder here.
Please keep me posted on the job front once you get settled, I would love to keep in touch
good luck and have a safe flight.
