[Gratuitus comment... I believe our learned colleague, z, to be an outlier and have greatly underestimated him. Granted, he guards his privacy more zealously than some--I do not at all--but taken in a broader context he has something indispensable going for him none of the rest of us have, including me: the luxury of time.
I dare say, if he were to commission an authorized autobiography of his life and times, regardless the length or cost, I would be first in line to purchase a copy. He [ordinarily] is a gentlemen of few words but the artful way he chooses to use them are a joy to read... this coming from an old whippersnapper who has effectively eviscerated ever rule he has devised, on more than one occasion.]
