We're never going to know whether (or not) the chicken preceded the egg. So why bother thinking about it? Such philosophical quandaries make great brain puzzles, but in terms of intellectual endeavour, there are better ways to use our time! Talking about questions we're better off avoiding, the big one, today, involves blame and responsibility. Since nothing positive will come from pointing fingers, take a deep breath and rise above a contentious issue. Do so, and you'll smooth the path towards a Happy New Year.
