 True.
 But, . . .
 is there a correlation (non-causal) between those who do not know the old
 saying(s), and those who are re-inventing remedial basic techniques for
 working with threaded fasteners? 
 On reflecting back, I don't believe anyone
ever taught me (in any
manner) the "turn in reverse to find the start of the thread" technique.
  I've done it so long now, I usually do it without even thinking about
it.  I suspect that I discovered the technique for myself shortly after
I thoroughly cross threaded some fastener in my youth.
I did get the chance to pass it on to my 42 year old daughter recently
when I was helping her assemble a small computer desk.  In that case the
"nuts" were plastic inserts in the wood of the bottom side of the desk
top, and I was unusually concerned about the possibility of cross
threading one of those.  She saw the advantage of the technique right
away once I pointed it out.  Maybe what the world needs is more/better
mentors ("Elmers" as I recall in the ham radio world).
 In 30 years of college "professorship", I have seen obvious changes in
 college students.
 It used to be that I could start my OS class with "DOS est omnis divisa in
 partes tres" and at least some of the class would understand the phrase
 and the analogy.
 Is the reduction in ability to spell, or differentiate homonyms, related? 
Could
spell checkers be to blame for some of that?
  I made a license plate frame that says "UC
Berkeley Aluminum"  (I also
 made a slightly variant one in case I ever have another British car)
 
Heh! I love it...  I assume the frames are made of aluminum/aluminium.
