Aging and age related pathologies are among the main medical problems of modern societies. Although aging is generally seen as an inevitable normal developmental period, I believe that its acceptence as a disease -even though it might not- will have many pragmatical consequences and break the mental barriers against studying it. There are many theories tested in the field of biogerontology. Free radical theory is the most studied one. But in the last few years there has been many controversial studies concerning the role of free radicals in aging. Decades long studies to find strategies aiming to postpone aging resulted only with a few successes like caloric restriction and rapamycin in model animals. Therefore we likely need a paradigm shift in the future. Therefore, in this book extreme plant longevity/plant aging and traditional medicine were emphasized as new areas to focus on in biogerontological studies. Interestingly they seem neglected so far. Current and past achievements of the field were also tried to be covered widely. I would like to thank all of the contributors for their very kind efforts that made this book a reality. I am grateful to Transworld Research Network team for kindly giving me the opportunity to edit this book and their professional work during the publication process.
