I'm curious how much of that is attributable to aging.

  It could possibly but when I studied math in college I got incredibly good at mental math. A lot of it is memory or number tricks and a bit of practice. I would say anyone can learn them regardless of age. I am many years out of college but even by the time I was in my mid twenties and a few years out of school my ability to do simple problems in my head went down drastically since I wasn't doing it nearly as often. Age may play a factor but probably not as much as you would think.
