@kraftie: Resilience under fire is a good thing certainly - so is knowing which fires are worth fighting, and which are not.
I tend not to argue the obvious
and I know that what's obvious to me at 63 wasn't at all obvious to me at 23, or 33, or even 43 in some instances
.
So... I share what I know *if* I'm reasonably sure of it, and if I think it might help. It might only make sense a decade or more down the road in some cases. That's good enough, because some other person, reading casually, might find something that helps them immediately. 
(And I've received a *lot* of help in just exactly that way. Much of it here, TBH!)
