Manu:
I've run into this many times in the past too... never really
thought
on it whether it's a problem that could actually be solved.
Sometimes one way to realize you have a problem worth trying to
solve is to push your mind sideways to a more naive state (in my
original post in this thread I was in that state).
Sometimes this is useful even when you search for a solution: the
word "ingenuity" in modern Italian sounds a lot like "essere
ingenuo", that means something like "being unsophisticated" in
English.
