This thread is to do with things you may not understand the whys or wherefores of certain "things"; but were afraid to ask in case the reason was bleedin' obvious and you didn't want to look a right plonker.
This is probably a hangover from when we were all in primary/junior/high school but were afraid to put our hand up lest the whole class laughs at us, even though the majority didn't know the answer either.
So don't be embarrassed - remember there is no such thing as a stupid question.
As Voltaire once said (he was a mate of mine ) "Judge a man by his questions rather than by his answers.", and the one I always like to quote is a Chinese proverb, which may have been Confucius, but he was a bit before my time.
"He who asks is a fool for five minutes, but he who does not ask remains a fool forever."
Doesn't matter how mundane it is, ask away.
So, here is my starter:-
Why is it that we/they continue to use lead on church roofs, which then gets stolen on a regular basis when modern materials that have been developed from say space exploration etc. must be a better/cheaper source than this ancient and now valuable metal?
