At any rate, you live.” – Douglas Noel Adams “I don’t want to get to the end of my life and find that I have just lived the length of it. I want to have lived the width of it as well.” – Diane Ackerman Acknowledgements It’s been a long road from starting the research to finishing this thesis, and I would have not been able to arrive without the aid and support of countless people over the past five years.
