assisted me with my statistics and never got angry as she showed me the same steps over and over again. I would also like to thank the research assistants who helped me with this project. Hillary Webb, Kim Roberts, and Brian Howland all helped in heartrate reduction. I would especially like to thank Scott Lebowitz who worked diligently on many aspects of the project from subject recruitment to data management. I would also like to thank those individuals and organizations who helped me to find participants for this study, including Beth McCauley; Anne Rottman, M.D.; Laura Hodges, P.T.; Orlando Stroke Club, Golden Gators; and the other seniors groups from local churches who allowed me to recruit subjects through their organization. And, of course, I would like to thank all of those individuals who spent the many hours required to participate in this project. Lastly, I would like to thank my family and friends who supported me and attempted to calm me down through all of my catastrophizing over the last three years. iii
