It occurred to me the other day that I haven't heard the expression, 'It's the gospel truth!' for a very long time. I don't think I have ever used it myself but I think if it was used today, say, on the radio, many people would wince slightly! Or perhaps they would feel a slightly somewhat subconscious wince! Anyway, just thought I'd mention it.
It depends on what camp you are in.Cross your fingers gives me the pain in the $%^&*
~TW~
Best only use uncrossed fingers or better still only use one finger.
Why you are going anywhere near your $%^&* with your fingers is your personal business of course!
