I quite agree Eric, although it's hard, if not impossible to define what you are saying. It's like knowing how far you can 'push' something before it breaks. My wife and I often have this discussion. Although I am a bit stronger than her, she is far more likely to break something whilst pulling, pushing or twisting than I am. I have always said that some people have a sort of feedback mechanism that tells them to lay off at just the right moment!
