Don't overlook that my description covers about 50 years worth of "notes." And in my line of work it was not that uncommon for someone to ask about stuff that you did ten or fifteen years - or longer - ago.

As to telling someone "before you croak" - if it ain't in writing, there'll be an argument about what you said. (Voice of experience.)

Of course, if it is written down but they (the right ones) can't find it at the proper time, it's pretty much like not even telling anyone.

But my notes are still for personal use. There ain't enough for the kids to have a decent fight about.
