Funny feeling

[J Mackrel Jones]

"The body learns what the mind ignores and can remember what the mind forgets:  When you get that funny feeling that  This might go wrong - Stop.  Look at what you're doing and make a change in favor of safety."    SAKOM
I have felt this once in a while - and felt the "sting of organic damage" when ignoring it while using a sharp tool.  Has anybody else noticed this funny feeling and been saved - or not - from injury by it?
