>>Come on, folks: how fantastically well-preserved Xi & I are for middle-aged geezers is not really the heart of this debate...

Sorry, Pet. You are correct. It is not the heart of the debate, but you open up a whole new can of worms.

Are Bruce Willis and Morrissey well-preserved middle aged geezers? Last time I saw a picture of Bruce Willis he looked like a well-preserved pickle and Morrissey was looking like a young Keith Richards.
