Not that I pay much attention to statistics like this, which are just a bunch of unreliable numbers. But this is a US study and they lead very different lives to the average UK citizen, so it's moot.
I retired at 57 so my odds look good, but I still think it's tosh. When I started my career I was told that people in my profession died on average 5 years after retirement, so statistically I've got 2 years left . . . who knows. I do know a lot of people who fit that statistic and died within that 5 year span, but they were smokers/drinkers/unfit and overweight.
Has that study taken any of those factors into account?
It's nonsense unless it's a clinical trial, carried out with a control set and it has to take into account each individual lifestyle as well, which is virtually impossible so it means nothing.
Just chill and enjoy your life and if you're worried about longevity don't sweat over Google articles, but do look at your diet, fitness, sleeping patterns and relaxation. Get those right and your chances improve dramatically. You can still get run over by a bus though
