A very interesting take on ‘cognitive decline’ and how it might be a measurement artifact. I sort of discuss it in a post on why thinking takes longer as you get older, it is interesting to see my opinion might have some science behind it.
Of course, as the author says, it might be old people grasping at straws to try to keep even with you young punks. However, keep in mind you young people: old age and treachery will always overcome youth and skill!
