David Sinclair - Lifespan

It was shortly after that conference that one of the world’s top scientists in the yeast field, Leonard Guarente of the Massachusetts Institute of Technology, came to Sydney on holiday to visit Ian Dawes. Guarente and I ended up at a dinner together, and I made sure I was sitting opposite him.

I was then a graduate student using yeast to understand an inherited condition called maple syrup urine disease. As you might imagine from its name, the disease is not something most polite people discuss over dinner. Guarente, though, engaged me in a scientific discussion with a curiosity and enthusiasm that was nothing short of enchanting. The conversation soon turned to his latest project—he had begun studying aging in yeast the past few months—work that had its roots in the workable genetic map that Mortimer had completed in the mid-1970s.

That was it. I had a passion for understanding aging, and I knew something about wrangling a yeast cell with a microscope and micromanipulator. Those were essential skills needed to figure out why yeast age. That night, Guarente and I agreed on one thing: if we couldn’t solve the problem of aging in yeast, we had no chance in humans.

In a wide-ranging interview to promote his memoirs, Lanzmann said of his masterpiece film about the Holocaust, “I wanted to get as close as possible to death. No personal accounts are told in Shoah , no anecdotes. It’s only about death. The film is not about the survivors.” “‘Shoah’ Director Claude Lanzmann: ‘Death Has Always Been a Scandal,’” Spiegel , September 10, 2010, http://www.spiegel.de/international/zeitgeist/shoah-director-claude-lanzmann-death-has-always-been-a-scandal-a-716722.html.

The study looked at three concepts about death that children come to understand before they are seven years old: irreversibility, nonfunctionality, and universality. M. W. Speece and S. B.

The film’s exhortations to make the most of every day took on a darker hue after the suicide of its star, Robin Williams. P. Weir, director, Dead Poets Society , United States: Touchstone Pictures, 1999.

The author argues that rather than focusing on cancer and cardiovascular issues, medical research should be focusing on “reducing ageing and age-related morbidity, thereby increasing both our health and our wealth.” G.

In a survey coconducted by the Economist , the majority of respondents from four countries expressed the wish to die at home, although only a small number thought that they would do so. With the exception of Brazilians, most felt that dying without pain was more important than extending life. “A Better Way to Care for the Dying,” Economist , April 29, 2017, https://www.economist.com/international/2017/04/29/a-better-way-to-care-for-the-dying.

My editor made me write self-centered things about myself to give me credibility. I hope she doesn’t see this endnote and make me delete it.

In 2018, my family and I made a pilgrimage to London to see the original account of Captain James Cook’s “voyage round the world” and the original Australian botanical specimens collected by Sir Joseph Banks. There were stop-offs to see Watson and Crick’s original model of DNA, fossils of early life, a Moai statue from Rapa Nui, a cross-sectional cut through a 1,500-year-old sequoia tree trunk, a statue of Charles Darwin, the Broad Street pump, Winston Churchill’s War Rooms, and the Royal Society, of course. Tracing the path of Cook along the lower east coast of Australia, or “New Holland,” as it was called then, it is obvious that Banks already had a colony in mind, one that would never forget him. Not only was the original site named Botany Bay, the coast was named “Cape Banks.” After exploring Botany Bay, the explorers’ tall ship, the HMS Endeavor , sailed north, past the heads of a harbor they called Port Jackson, which, thanks to its much deeper waters and the presence of a stream to supply fresh water, ended up being a far superior site for Governor Phillip to start a penal colony eight years later.

The Spanish explorer and conquistador’s search for the mystical spring known as the Fountain of Youth is apocryphal, but it makes for a good story. J. Greenspan, “The Myth of Ponce de León and the Fountain of Youth,” “History Stories,” April 2, 2013, A&E Television Networks, https://www.history.com/news/the-myth-of-ponce-de-leon-and-the-fountain-of-youth.

According to the Creation Wiki: the Encyclopedia of Creation Science (a website of the Northwest Creation Network, http://creationwiki.org/Human_longevity), in Genesis, most of us once got to 900 years, then we didn’t. Then most of us got to 400, then we didn’t. Then most of us got to 120, then we didn’t. In more recent times, as Oeppen and Vaupel have written, “Mortality experts have repeatedly asserted that life expectancy is close to an ultimate ceiling; these experts have repeatedly been proven wrong. The apparent leveling off of life expectancy in various countries is an artifact of laggards catching up and leaders falling behind.” J. Oeppen and J. W. Vaupel, “Broken Limits to Life Expectancy,” Science 296, no. 5570 (May 10, 2002): 1029–31.

There is some debate as to what constitutes verifiable age. There are humans who have claimed, and provided considerable evidence, of being of great age, but who don’t have formal Western-style records of their year of birth. In any case, these people are one in a billion, if that. In November 2018, the Russian gerontologist Valery Novoselov and the mathematician Nikolay Zak claimed that after much research, they believe that Jeanne Calment’s daughter, Yvonne, usurped Jeanne’s identity in 1934, claiming that the daughter had died instead of the mother to avoid paying estate taxes. The debate continues. “French Scientists Dismiss Russian Claims over Age of World’s Oldest Person,” Reuters, January 3, 2019, https://www.reuters.com/article/us-france-oldest-woman-controversy/french-scientists-dismiss-russian-claims-over-age-of-worlds-oldest-person-idUSKCN1OX145.
