John (Wednesday Letters), you do indeed worry too much. The secret to a happy and peaceful life is to never worry about anything until it happens, and then you're too busy dealing with it to worry. Oh damn... now I'm worried about you...

During my degree I had a Maths question that couldn't be solved so I spent my time working out what the question should have been and passing this back to the tutor overseeing the exam. Did I get any extra marks for this? Sadly no, but I'm nearly over it now...

Reading this story about rats on a plane, I'm wondering how rare something is if it's never happened before? At what tipping point does "never" become "rare"? Also, "rats on a plane" sounds like a good plot-line for a movie.
