Zambuck,
The next time your good lady alleges that your brain - or other vital organ - appears to have shrunk, you can remind her that her diagnostic technique is perhaps less reliable than the one for determining the point at which middle-age has clearly been reached in womanhood. It is that point where the narrow waist and broad mind change places!
Light blue touch paper and retire. I jest - of course.
Best wishes,
