The Lived Experience of Being a Hundred Years and Over
The lived experience of being a hundred years and over By Ashwina Naiker-Ratan A thesis submitted to Victoria University of Wellington in fulfilment of the requirements for the Degree of Master of Health Research Victoria University of Wellington 2016 ABSTRACT The twentieth century has seen a decline in mortality after the age of eighty and an increase in survival rates of the oldest of the old. Centenarians (people over a hundred years of age) are the fastest growing group of this population in developed countries; however qualitative research on the oldest of the old is limited. The primary aim of this study was to gain an understanding of the essence of lived experiences and meanings of extended longevity as perceived by centenarians. It also aimed to explore the role of lifestyle characteristics, family, social, health and cultural factors in regards to their prolonged existence. The research was conducted with ten centenarians aged between 100 and 106 years living in the Lower North Island namely Wairarapa, Kapiti and Wellington of Aotearoa New Zealand. Biographical Narrative Interpretive Method of inquiry was used to guide the data collection through face-to-face interviews using unstructured open ended questions. Colazzi’s phenomenological framework was employed for data analysis. There were common patterns throughout the life stories related by the centenarians and resilience and acceptance of life was notable. The centenarians spoke nonchalantly about their experience of turning a hundred, describing their birthday as; “Just another day.” Positive personalities and resilient nature were prominent features of the participants who all expressed a sense of acceptance and satisfaction with life and contentment with living in the present. -
Biogerontology: a Novel Tool to Stay Healthy in Old Age
MoPAct Policy Brief: 5 Biogerontology: a novel tool to stay healthy in old age Policy priority Healthy lifestyle interventions in particular regarding nutrition and vaccination need to be implemented early in life with a lifecourse perspective. Summary: Key findings: • Accumulating evidence from experimental studies shows that aging is not inevitably linked with the development of chronic diseases. • Only 20-25% of healthy life expectancy (HLE) is predetermined by genes; lifestyle and environment play a major role. • Age-associated accumulation of molecular and cellular damage can be prevented or greatly delayed by lifestyle interventions e.g. dietary manipulations. • Classical strategies (e.g. nutrition, exercise, vaccination) require broad communication to public. • Novel strategies (e.g. dietary interventions, novel drugs, stem cells) need successful translation from the understanding of molecular mechanism to animal models to clinic. • To be successful interventions need to be started early Figure 1. Strategies to increase HLE. (1) Classical interventions include nutrition, exercise, vaccination, no smoking/alcohol/drugs.

Ralph: Longevity Extension Longevity Extension from a Socioeconomic Perspective: Plausibility, Misconceptions, and Potential Outcomes Eric Ralph Introduction In the last several decades, a significant amount of progress has been made in pursuits to better understand the process of aging and subsequently gain some level of control over it. Current theories of aging are admittedly lacking, but this has not prevented biogerontologists from drastically increasing the longevity of yeast, drosophilae, worms, and mice (Vaiserman, Moskalev, & Pasyukova 2015; Tosato, Zamboni et al. 2007; Riera & Dillin 2015). Wide-ranging successes with gene therapy and increased comprehension of the genetic components of aging have also recently culminated in numerous successes in extending the longevity of animals and the first human trial of a gene therapy to extend life through telomerase manipulation is already underway, albeit on a small scale (Mendell et al. -

Article Oxylipin biosynthesis reinforces cellular senescence and allows detection of senolysis Graphical abstract Authors Christopher D. Wiley, Rishi Sharma, Sonnet S. Davis, ..., Marco Demaria, Arvind Ramanathan, Judith Campisi Correspondence [email protected] (C.D.W.), [email protected] (A.R.), [email protected] (J.C.) In brief Senolytics, transgenic, and pharmacological interventions that selectively kill senescent cells are currently in clinical trials aiming to treat age-related degenerative pathologies. Here, Wiley et al. discover that senescent cells produce multiple signaling lipids known as oxylipins. One oxylipin, dihomo-15d-PGJ2, promotes features of senescence by activating RAS and is released from cells during senolysis, serving as the first biomarker of the Highlights process in culture and in vivo. d Senescent cells make several oxylipins, dihomo- prostaglandins, and leukotrienes d Dihomo-15d-PGJ2 is intracellular during senescence and released during senolysis d Dihomo-15d-PGJ2 activates RAS, promoting senescence and the SASP d Positive feedback between prostaglandins, RAS, and p53 maintains senescence Wiley et al., 2021, Cell Metabolism 33, 1–13 June 1, 2021 ª 2021 Published by Elsevier Inc. https://doi.org/10.1016/j.cmet.2021.03.008 ll Please cite this article in press as: Wiley et al., Oxylipin biosynthesis reinforces cellular senescence and allows detection of senolysis, Cell Metabolism (2021), https://doi.org/10.1016/j.cmet.2021.03.008 ll Article Oxylipin biosynthesis reinforces cellular senescence and allows detection of senolysis Christopher D.

After a lot of patient explanation, publication of scientific results, conferences, and time, our community persuaded enough scientists of the feasibility of the damage repair approach to move SENS and SENS Research Foundation from the fringes of scientific respectability to the vanguard of a mainstream community of scientists developing medical therapies to tackle human aging. -
HCB 524 — Transhumanism
HCB 524 Special Topic in Bioethics Fall Semester, 2019. Tuesdays 6-8:30pm. Instructor of Record: Adam Sepe, MA, MLS(ASCP)cm [email protected] Course Description: Transhumanism and [Human?] Dignity. Throughout human history — and prehistory for that matter — technological advancement has drastically altered every aspect of human life. Most of us will say that many advents — such as cooking and the wheel — have been largely, if not entirely, beneficial. Would we say the same of all technology? Surely each of us can list technologies that have, in the very least, some considerable downsides. So while history and experience can tell us that some technologies are beneficial and that some other technologies are harmful, how can we know what kind of impact future technology will have? For now we can’t, and so all we can do is try, to the best of our ability, to imagine such futures and develop our technology with these considerations in mind. ‘Transhumanism’ refers a diverse collection of ideas that have one at least thing in common: through future technology, humanity will be fundamentally altered to an unprecedented degree. Some even believe there will come a time when, through our own action, the word ‘human’ will be obsolete; that we will be succeeded by entities (or an entity) for which ‘human’ does not apply. Most people who identify as transhumanists are, to varying degrees, proponents of such technology. They are in favor of such alterations and they argue that these will be beneficial. In this course, we will take a critical look at transhumanist claims. -

With the astonishing biotechnological powers that are increasingly reshaping nature and human nature, are we in a “transitional state” (transhumanism) en route to a redesigned posthuman future in which current limitations are overcome? Four centuries ago, Francis Bacon announced the biological utopia of the future in his The New Atlantis, replete with fountains of youth and chimeras. The term “transhumanism” was originally coined by the British biologist philosopher Julian Huxley in a 1957 essay to capture the ways in which social institutions could supplant evolution in refining and improving the species, as could technology. Sensory perception, emotive ability, cognitive capacity, health and life spans could all be augmented. The term was taken over in the 1990s by British philosopher Max More, who began defining the principles -
Chapter 9. Myths of Life Extension
Chapter 9. Myths of Life Extension Ever since humans became fully aware that they will get old and die, individuals must have wondered about the possibility of extending longevity, or achieving immortality on earth. This has resulted in innumerable myths relating to supposed examples of life-extension, one of the most notable being the 969 year lifespan of Methuselah, as recorded in the Bible. Christian fundamentalists are liable to say that in those days people lived much longer than they do today! These are many other claims, and far too many to list here. The Guiness Book of Records has stated that maximum lifespans of people and animals are some of the hardest records to document. Some of the claims of human longevity have occurred in the 20th century, and as in some cases they were initially accepted by scientists, and they provide good examples of how people are deceived. Many people living in the Caucasus region of the ex-Soviet Union claimed their ages were over 120 years, or even 160 years. There was even a touring troup of centenarian dancers, so it is not surprising the claims received wide publicity, and also wide acceptance. The oldest people were usually males which is intrinsically unlikely as human females live longer that males. Careful scrutiny of these cases, particularly by the gerontologist Zhores Medvedev, has shown that none are backed up by reliable records. In some cases, individuals took on the identity of their father, in others they exaggerated their age to escape military conscription, or they simply added on years, because the societies in which they lived respected the wisdom and experience of very old people. -
Prospects for Curing Aging
REJUVENATION RESEARCH Volume 17, Number 5, 2014 ª Mary Ann Liebert, Inc. DOI: 10.1089/rej.2014.1580 The Scientific Quest for Lasting Youth: Prospects for Curing Aging Joa˜o Pedro de Magalha˜es Abstract People have always sought eternal life and everlasting youth. Recent technological breakthroughs and our growing understanding of aging have given strength to the idea that a cure for human aging can eventually be developed. As such, it is crucial to debate the long-term goals and potential impact of the field. Here, I discuss the scientific prospect of eradicating human aging. I argue that curing aging is scientifically possible and not even the most challenging enterprise in the biosciences. Developing the means to abolish aging is also an ethical endeavor because the goal of biomedical research is to allow people to be as healthy as possible for as long as possible. There is no evidence, however, that we are near to developing the technologies permitting radical life extension. One major difficulty in aging research is the time and costs it takes to do experiments and test interventions. I argue that unraveling the functioning of the genome and developing predictive computer models of human biology and disease are essential to increase the accuracy of medical interventions, including in the context of life extension, and exponential growth in informatics and genomics capacity might lead to rapid progress. Nonetheless, developing the tools for significantly modifying human biology is crucial to intervening in a complex process like aging. Yet in spite of advances in areas like regenerative medicine and gene therapy, the development of clinical applications has been slow and this remains a key hurdle for achieving radical life extension in the foreseeable future.
