Old age demands to be taken very seriously–and it usually gets its way. It’s hard to be cavalier about a time of life defined by loss of vigor, increasing frailty, rising disease risk and falling cognitive faculties. Then there’s the unavoidable matter of the end of consciousness and the self–death, in other words–that’s drawing closer and closer. It’s the rare person who can confront the final decline with flippancy or ease. That, as it turns out, might be our first mistake.
Humans are not alone in facing the ultimate reckoning, but we’re the only species–as far as we know–who spends its whole life knowing death is coming. A clam dredged from the ocean off Iceland in 2006–and inadvertently killed by the scientists who discovered it–carried growth lines on its shell indicating it had been around since 1499. That was enough time for 185,055 generations of mayfly–which live as little as a day–to come and go. Neither clam nor fly gave a thought to that mortal math.
Humans fall somewhere between those two extremes. Globally, the average life span is 71.4 years; for a few lucky people, it may exceed 100 years. It has never, to science’s knowledge, exceeded the 122 years, 164 days lived by Frenchwoman Jeanne Calment, who was born when Ulysses S. Grant was in the White House and died when Bill Clinton lived there.
Most of us would like a little bit of that Calment magic, and we’ve made at least some progress. Life expectancy in the U.S. exceeds the global average, clocking in at just under 79 years. In 1900, it was just over 47 years. The extra decades came courtesy of just the things you’d expect: vaccines, antibiotics, sanitation and improved detection and treatment of a range of diseases. Advances in genetics and in our understanding of dementia are helping to extend our factory warranties still further.
None of that, however, changes the way we contemplate the end of life–often with anxiety and asceticism, practicing a sort of existential bartering. We can narrow our experiences and give up indulgences in exchange for a more guardedly lived life that might run a little longer.
But what if we could take off some of that bubble wrap? What about living longer and actually having some fun? A Yale University study just this month found that in a group of 4,765 people with an average age of 72, those who carried a gene variant linked to dementia–but also had positive attitudes about aging–were 50% less likely to develop the disorder than people who carried the gene but faced aging with more pessimism or fear.
There may be something to be said then for aging less timidly–as a sort of happy contrarian, arguing when you feel like arguing, playing when you feel like playing. Maybe you want to pass up the quiet of the country for the churn of a city. Maybe you want to drink a little, eat a rich meal, have some sex…
