I've heard it said that the first thing to
deteriorate as you get old is the eyesight. I don't remember what the second thing

I also don't remember the name of a tool that (IIRC) Fons created, which had a very
simple GTK GUI, into which you can direct a JACK stream of float's, and it lights up
an indicator if there are NaN's, denormals, etc etc.
