Die Studie findet Amerikaner mit weniger Ausbildung schneller als Gleichaltrige mit mehr Schulbildung, und die Lücke ist in den letzten 30 Jahren gewachsen. Anstelle des chronologischen Alters untersuchte die Studie das biologische Alter, was misst, wie sich der Körper im Laufe der Zeit verändert, einschließlich der Funktionsweise von Organen und Systemen.

The brain is basically a muscle that is connected to everything in your body. So, this makes sense. Better brain health = healthier person.
Use it or lose it. It’s very true, especially for human brain.
Short version: Being poor is stressful. Stress is ageing.
I wonder whether they controlled for child rearing, given the association between higher education and delays in parenting.
For those too lazy to read the article: the difference in the biological aging is about 2 years (when comparing someone who has less than high school education, to someone with a college degree), and that’s comparing only people aged 50+.
I’m curious if the life expectancy for blue collar workers who have higher incomes end up living longer or does the level of income not cause a change.
Why is everyone talking about brains? The study is about aging in general. The whole body.
They don’t go into detail about how the ink between aging and education works. My informed guess is that it has to do with income, opportunities, and health access. Affording healthy food & activities, working in jobs that don’t ruin your body, being able to afford medication and doctor visits.
Curious to know the breakdown between people with bachelor’s, master’s, and PhD or MD degrees. A few years of grad school feels like it has aged me by at least 10 years.
