I think OP used "..." because he has some sympathy. He could use better word than "smarter", but it is indeed a certain kind of smartness.
I am sure that when I will get old I will become less capable and I am worried about this. Because looking at birth rates and inverted population pyramids around me signify that I will be an old man in the sea of old people. A conman's dream I suppose. It is not that I don't have sympathy saying all this (just as I think OP thinks) for those other people, quite the opposite, because if I will live long enough I will be one of them.
