It is not a spurious correlation, the two statistics are causally related. However, individual cases may vary, which is a problem with looking at aggregate statistics in general, and which is not addressed by your spurious correlations accusation.
Fair point. I still imagine there's a larger deviation between the aging population and the slowed down population than most people think - and especially large enough to dispel the idea that we must stigmatise people who slow down because of it.
