The operative word here, is "proven," isn't it, dear Glad?
Thank you A Guest - that is why I used the word 'proven.' One has to be quick in the arena.
It's all the speculation that causes me to pause.
I doubt if you will ever pause, but each of us marches to a different drum, and the variety of tempos allows us to find a pace that suits us.
Peace to you, and may your gods go with you.
