Granted, people's appearances can change with age --- mine certainly has --- but it still looks awfully fishy.
I have a certain amount of "face blindness" --- don't know what caused it, it's come on in the past few years, and, yes, it is an equal-opportunity thing, I experience it with Europeans, Africans, Asians, and everyone else --- so I've developed the habit of studying people's facial features, things like eyebrows, ears, noses, and so on. When something is a little "off", I pick up on it. It's a compensation strategy. At my son's former school, many of the "soccer moms" looked exactly alike to me. And on college campuses, many of the coeds are basically (no pun intended) clones of each other.
