Science Writers Contribute To The Conversation

As we have more conversation in 2014 and beyond, it will definitely be improved with the science writers we have been following the last few years, and their successors who follow in their footsteps.

For example, we appreciate Virginia Hughes and the kind of writing that she publishes all over the place, and which National Geographic‘s Phenomena website collects, with this most recent example of hers:

An Old and Optimistic Take On Old Age

I’ve been reading and thinking a lot lately about the process of aging. Many scientists who study it argue — quite convincingly — that it’s the most important scientific topic of our time. In his 1997 bestseller Time of Our Lives, biological gerontologist Tom Kirkwood writes that the science of human aging is “one of the last great mysteries of the living world.”Over the past century, Kirkwood notes, developed countries have used preventative and offensive tactics to slash infant mortality, smoking, and accident rates, and to conquer most infections. In the 1880s, the top causes of death were respiratory diseases (like tuberculosis and influenza) and digestive diseases (like cholera and typhoid), and life expectancy was around 46 years. Today, we’re living three decades longer and dying of illnesses — such as cancer, stroke, and dementia — that most of our ancestors didn’t grow old enough to get.

Perhaps because people are living longer and longer, we tend to think about aging as a modern phenomenon. “Data from the Census Bureau tell us that there are currently around 39 million Americans age 65 and older, up from 25.5 million just 30 years ago,” notes the website of the National Institute on Aging. “This population explosion is unprecedented in history, and the resulting demographic shift is causing profound social and economic changes.”

Though it may be getting a surge of scientific and cultural attention, aging isn’t a new problem. Far from it: Philosophers have been fretting over old age for thousands of years, asking essentially the same thorny, metaphysical questions that get asked today. This became obvious to me this weekend while reading The Nature of Man, a fascinating and surprisingly eloquent book published in 1903 by Russian biologist Élie Metchnikoff.

The book’s basic premise — that science and reason can lead to optimism and happiness, despite religious arguments to the contrary — is interesting in its own right. And I’ll get into how it relates to aging. But Metchnikoff’s argument is even more interesting if you know a bit about his personal life.

When he was 18 years old, Metchnikoff married a woman with tuberculosis. She was sick enough on their wedding day to be carried to the church, and stayed sick for the next decade before dying in 1873. Devastated, Metchnikoff tried to kill himself with an opiate overdose. He married again in 1875, and five years after that his second wife caught typhoid fever. She almost died, and Metchnikoff again attempted suicide.

Metchnikoff’s depression lifted in 1883 with the discovery that would make him famous (and later earn him the Nobel Prize). He was the first to identify phagocytes, cells of the immune system that engulf and destroy invading microbes. He became friendly with Louis Pasteur, whose discoveries of microbes and vaccines had prevented all kinds of sickness and death. In 1888, Metchnikoff was given an appointment at Pasteur’s prestigious research institute, in Paris, where he worked until his death in 1916.

Given Metchnikoff’s life experiences, you can understand why he may have felt reverence and gratitude for science. This was the era, after all, when scientists like Metchnikoff and Pasteur and many others were figuring out how pathogens worked and, with that scientific understanding, developing methods to fight them off.

The premise of Metchnikoff’s The Nature of Man is underscored in its subtitle, “Studies in Optimistic Philosophy.” In it Metchnikoff explains his optimism not only about science’s ability to fight disease, but to ward off a much more menacing threat: aging…
