A new model to predict the life expectancy of older people relies less on their specific disease diagnoses and more on factors such as the ability to grocery shop, the amount of certain small cholesterol particles circulating in their blood, and whether they never or only occasionally smoked.
The findings provide a way to predict whether a person over the age of 70 is likely to live two, five or 10 years.
"This study was designed to determine the proximal causes of longevity—the factors that portend whether someone is likely to live two more years or 10 more years," said Virginia Byers Kraus, M.D., Ph.D..
Kraus and colleagues launched their inquiry at an opportune time, having been directed to a cache of 1,500 blood samples from a 1980s longitudinal study that enrolled older people.
The researchers were able to delve into health factors to identify a core set of 17 predictive variables that have a causal impact on longevity.
The analysis found that a leading factor associated with longevity across each of the study's benchmarks—two-, five- and 10-years after participants had their blood drawn—was physical function, which was defined as an ability to go grocery shopping or perform housecleaning chores. Surprisingly, having cancer or heart disease was not among the main predictors.
For older people living two years beyond the time their blood had been drawn, the leading factor associated with longevity was having an abundance of high-density lipoprotein (HDL) cholesterol—and not just any HDL lipids, but high volumes of very small HDL particles.
At five years beyond the original blood draw, just being of a younger age was predictive of longevity, along with cognitive function. And among the longest survivors—those living 10 years—the best predictor was a person's smoking history, with non-smokers faring best.

Exercise builds mental toughness. It sends a message to every fiber of your being that you are going to fight.
Compare that to your mental attitude when you are feeling down or discouraged.
Determination makes all the difference...and that is what you build when you exercise.
Wait a minute...I mentioned diet also.
Okay, that's important too.;-)
Cut the carbs and sugar and see if you don't feel better. And see if your mind isn't clearer.
I have been on keto for years, but recently had slipped a wee bit. I noticed that I wasn't in a state of ketosis.
I got back on the diet last week and my mind is significantly less foggy. In fact, the difference is downright shocking.
Good points!
Where is the list of the 17 factors?
“Exercise and diet.” Bingo. Every person who studies a book on exercise and exercises two hours a day and then studies a book on nutrition and eats three solids meals a day will live to 120. Exercise: “total muscle fatigue” is the secret to a long life. Nutrition: asparagus is the secret ingredient to a healthy life. Key: study.
Doing physical activity, walking, jogging, swimming, etc are best for brain health and preventing dementia, alzheimers, parkinsons, etc
Much better than crossword puzzles and reading
This is the study:

How do you tell?
Urinate on keto strips. I keep them on hand but forget to use them.
My dad and his dead both smoked like chimneys and lived to 78 and 79 respectively. And both ate the “bad” foods, bacon, eggs, lard, butter, etc.
Ping
This?
“… just being of a younger age was predictive of longevity, along with cognitive function.”
Who does the editing and proofreading for this stuff?
I never smoked, but both my parents and my three siblings did. They all died between the ages of 51 and 74. I turned 75 in August. Both my parents and my second-oldest sister died of lung cancer. Five years before she was diagnosed with lung cancer, that sister was diagnosed with four brain aneurysms. They operated on her inner carotid artery on the side where the biggest aneurysm was, and tied it off. That stopped the flow of blood to that aneurysm, and two others. She had one left in the back of her head they were keeping an eye on. As soon as she was diagnosed with the aneurysms, she stopped smoking cold turkey. Never picked up another cigarette. My brother died the youngest from a massive heart attack. He stopped smoking after his first heart attack at the age of 48. The oldest sister died at the age of 74, of a stroke. I was the baby, and although I never smoked, I have health issues that none of them ever had.
My father and mother both smoked Camels their whole life. My father worked on the NY Central Railroad, got up every morning at five, and cooked himself a big breakfast with bacon, or salt pork and eggs, before getting the bus to go to work. We didn't have a car. We used butter in the house too. My Dad kept a jar of bacon grease in the fridge that he would use to fry things up in. On Saturdays, he'd make his own meatballs, fry up Italian sausage, (we weren't Italian), and make spaghetti sauce. If there were pork chops or pork steak left over from a meal during the week, he'd throw those in the sauce. Sometimes he'd get pork hocks, fry them up in bacon grease, and throw those in the sauce. He was the only one who ate them. My Dad died in 1978, at the age of 72 from lung cancer. My mother died of lung cancer at the age of 69 in 1990.
My dad is 91, my mom 92. My dad is sharp, my mom has dementia which just set in about a year ago. My mom’s older brother, 96, died two days ago. My great grandmother lived to be 98, my grandfather’s sister - 106.
Most of them were active physically, but also mentally. Until a month ago, my uncle was tinkering with his farm equipment and old cars.
“Exercise: “total muscle fatigue” is the secret to a long life.” -— Unless you are a young male athlete who has been vaccinated. There are no keys. Good or bad attitude, junk or healthy food, exercise or longing about... I have seen people whose length of lives seemingly had little to do with anything known about their behavior.
Just looked up my last lipid panel HDL = 75
Non smoker..no alcohol no red meat...Mediterranean diet and fish, work out 2 times a week, not too bad for 80.
Being content with present life, being happy or proud to be yourself also figures into a long life.
Have you noticed how many successful, professional musicians seem to live for a long time? Quincy Jones is in his 80’s. Paul McCartney as well. Willie Nelson, still burning his blunts.
Classic Minimalist Phillip Glass in his 80s and still conducting.
An actor: Clint Eastwood.
Even Cher sets an example.
