The timing of this thread and the question posed is interesting. Just yesterday I came across a 1985 newspaper item about a proposed layoff in our agency. There is a large picture of yours truly and I have a very dark head of hair but also a grey beard.
I think the gray on my head really got started about the time I met some of you on the old SBCnet around 1988. For some years I described my hair a pepper and salt as Trudy starting in 1993 progressed through a B.A. an M.Div, and a second masters it became more frosty it is now more salt than pepper and I wish it would just go ahead and get white. But at least, 2months short of my 81st birth day, I still have a full head of hair.
