About a month ago a study (abstract) was published about how a father's age affects the psychiatric health of his children. Due to a misleading press release about the study's results, it was widely reported that children born to father over 45 years of age were 3.5 times more likely to have autism, 13 times more likely to have ADHD, 2 times more likely to have a psychotic disorder, 25 times more likely to have bipolar disorder, and 2.5 times more likely to have suicidal behavior or a substance abuse problem.
But statistical analysis is hard and non-intuitive, particularly for people who aren't expert statisticians. It turns out that the real-life rates of psychiatric problems are significantly less, putting this most recent study's results in line with those of previous related studies.

"are there no disadvantages (other than chance of parent dying while child is still young) to fathering while old?"
In my 30s, chasing them around the house felt a lot more exhausting than it appeared watching 20s do the same.
On the other hand my 30s were a lot more financially stable than my 20s, so it likely balances out.
More exercise, but no money related stress?
