So few thoughts come to me that I think when one does I should perhaps make a note of it. My wife has just handed me a quote from Ecclesiastes 7:12 - I have no idea why but presumably she thinks it might be of benefit , and so if this is true, why not share it with a wider audience. Anyway here it is for what it is worth:

"Wisdom is a shelter, as money is a shelter, but the advantage of knowledge is this:

that wisdom preserves the life of its possessor."
