The title kinda undersells the intersectional nature of the study, but the article seemed a surprisingly good summation.
The data isn't just from a handful of people either which I'd first wondered:
The study utilized data from the Health and Retirement Study. This is a large, long-running survey that represents the population of older adults in the United States. The analysis focused on 3,586 participants who provided blood samples in 2016.
I'm just a random, but I've seen it as well over there last few weeks. Much more obvious when browsing by hot or new, and then the author isn't findable from dbzero anymore. Or if they are, it's the only post, it's bait, and then they disappear. Hard to track.
