"There are few measures of human progress more astonishing than this,” says an excerpt from the book “Extra Life: A Short History of Living Longer” that ran recently in The New York Times Magazine.
"If you were to publish a newspaper that came out just once a century, the banner headline surely would — or should — be the declaration of this incredible feat. But of course, the story of our extra life span almost never appears on the front page of our actual daily newspapers, because the drama and heroism that have given us those additional years are far more evident in hindsight than they are in the moment.
"That is, the story of our extra life is a story of progress in its usual form: brilliant ideas and collaborations unfolding far from the spotlight of public attention, setting in motion incremental improvements that take decades to display their true magnitude."
The book’s author, Steven Johnson, also is a host of a four-part PBS/BBC series of the same title that’s airing this month.
"When the history textbooks do touch on the subject of improving health, they often nod to three critical breakthroughs, all of them presented as triumphs of the scientific method: vaccines, germ theory and antibiotics,” says Johnson.
"But the real story is far more complicated. Those breakthroughs might have been initiated by scientists, but it took the work of activists and public intellectuals and legal reformers to bring their benefits to everyday people. From this perspective, the doubling of human life span is an achievement that is closer to something like universal suffrage or the abolition of slavery: progress that required new social movements, new forms of persuasion and new kinds of public institutions to take root.
"And it required lifestyle changes that ran throughout all echelons of society: washing hands, quitting smoking, getting vaccinated, wearing masks during a pandemic.”
Johnson poses the question whether the trends behind these positive changes will continue.
"All those brilliant solutions we engineered to reduce or eliminate threats like smallpox created a new, higher-level threat: ourselves,” he says. "Many of the key problems we now face as a species are second-order effects of reduced mortality."
For example, "Extending our lives helped give us the climate crisis,” Johnson says. “If we had invented steam engines and coal-powered electrical grids and automobiles but kept global population at 1800 levels — climate change would be much less of an issue. There simply wouldn’t be enough humans to make a meaningful impact on carbon levels in the atmosphere.”
Well, let’s see what future the scientists, activists, intellectuals, reformers and we “everyday people” create.
