It is a bit curious, but the most difficult element of this book to write may be this acknowledgment. Not because I have so few to thank, but because I have so many. The number of family, friends, mentors and colleagues who have unselfishly shared their wit and wisdom with me over many years is humbling. I have been, and remain, the grateful beneficiary of their grace, good humour and professionalism. There are a fewwhom Iwish to single out for particular thanks. First and foremost, my family who have always been available to listen and to help me put challenges in perspective. They have been unstinting in their encouragement. I am also grateful to Prof. Hugh Kindred (Emeritus) and Prof. Robert J. Currie for their early guidance, continued mentorship and unwavering friendship. A special thank you as well to Dr. Ksenia Polonskaya, Dr. Debra Haak, Dr. Lucie Guibault and Basil Alexander. Their support and willingness to share their time whenever I needed to discuss an issue or wanted a second pair of eyes to look over a draft have been invaluable.
