I skimmed through it. Though, note, I didn’t critique it based on my reading, I noted one of its conclusions. It’s a serious study by well qualified PhDs in their field so criticizing it based on a very short web forum summary isn’t fair.
Another point the study found, that I hadn’t mentioned, was that parental divorce while the kids were still children statistically has also been shown to lead to a shorter lifespan for the children of the divorcees.
